Elena Gilbert may have a hard time choosing between the Salvatore brothers on The Vampire Diaries, but for a long time, Nina Dobrev was Team Ian Somerhalder.

The co-stars were a match made in TV heaven and became an adorable power couple soon after the show took off. They were private about their relationship for its 3-year time span, but openly affectionate at times, making TVD fans ‘round the world swoon.

Though they broke up in May 2013, it reportedly didn’t last long. On November 12, 2013, a report surfaced that they’re hooking up again, fresh on the heels of them hugging and looking at each other lovingly on the red carpet of their show’s 100th episode celebration.

To give you the full spectrum of Nian’s relationship, we’ve put together a timeline starting from the first sign of their coupling. The future of their relationship is still TBA, but fingers crossed that they, like Delena, find their happily ever after.

November 2010: Testing the Waters Down Under

Eyebrows really started to raise about the potential hook-up alert between Nina and Ian back when they were spotted spending downtime Down Under together, bonding over the Daintree Rainforest and the Great Barrier Reef. The romantic locale served as a perfect place for the duo to test the waters between them… literally. They were even photographed snorkeling together!

February 2011: Valentine’s Day Confusion

By Valentine’s Day, all eyes were on Nina and Ian to see whether the pair had stepped out of the friend zone. While they were reportedly seen “canoodling”and “focused on each other” at a restaurant near Atlanta for the special occasion, some mixed signals came by way of Ian’s tweet, which unromantically referred to the holiday as “corporate” and “a conspiracy of florists and chocolatiers.” To be fair, he also admitted the day serves as a good excuse to spread a little love.

March 2011: Nina Puts the Kibosh on the Romantic Buzz

A month later, Nina seemed to flat-out deny the romance rumors to Teen Vogue but admitted to understanding how people could suspect they were an item. “A lot of people who work together end up dating, so it wouldn’t be unusual,” she said, “but I’ve never dated anyone I’ve worked with.” To us, that sentence came with an unspoken caveat of “…yet.”

April 2011: Cozying Up at Coachella

Despite Nina’s recent denial of their involvement, she and Ian were spotted looking awfully cozy at the Coachella Music Festival that April.

April 2011: Whose Hat is That?

Couples who spend a lot of time together begin to look and dress alike. So, when Nina was seen sporting Ian’s cute newsboy cap just two days after he’d had it on, it seemed like it could be more than just a friendly gesture.

May 2011: Paris Is for Lovers and Moms

It’s serious stuff when the ‘rents get involved, so when Nina and Ian were pictured visiting Paris alongside both of their mothers, both wearing smiles for days and being adorably touchy-feely with each other while sightseeing in the City of Light, it became pretty clear that their relationship was poised to reach heights rivaling the Eiffel Tower itself.

June 2011: Little Red Dress

When the 2011 MTV Movie Awards came along and Nina was spotted wearing a dress similar to that of Twilight star Kristen Stewart, a lot of folks began to compare the two starlets. But for Ian, Nina was the clear winner. He took to Twitter to compliment the lady in red, writing, “Uhh, Nina gets my vote. That dress is like skin-tight wrapping paper around a beautiful gift! Wow.” Who else thinks it sounded like he wanted to be the one to unwrap her?

June 2011: Stepping Out Hand-in-Hand

The couple seemed to formally come out as a couple when they arrived for the 2011 MuchMusic Awards hand-in-hand, and both were positively glowing. Ian even name-dropped her as the person he was most excited to see. It was a coronation of sorts for what has become one of TV’s reigning hottest off-screen couples, especially since they were spotted sharing a smooch behind-the-scenes. Still, nothing was officially official just yet.

July 2011: Summer Lovin’ at Comic-Con

The trail of clues continued to be riddled with witnessed displays of affection between the two, as they were seen during July’s San Diego Comic-Con event together and “inseparable,” with  Ian seeming “very protective” of his lady as he fetched them drinks. The party reportedly carried over to the Camp Playboy Bash, where they were sleuthed sharing kisses and stroking one another’s lovely locks.

September 2011: Emmys Arm Candy

With all of the couple-y behavior that had been going down between Nina and Ian all year, some expected the two to walk arm-in-arm down the red carpet of the 63rd Primetime Emmy Awards. But Nina faced the media solo and remarked, "Ian is here somewhere, somewhere on the red carpet. He's definitely — if I was standing next to him I would be his arm candy, but um, yeah, I guess that's all I can say right now...” While they wound up posing for a few photo ops together later on in the night, they didn’t give a definitive answer to the question of their coupledom by their red carpet behavior. But aha! After the awards show, the duo hit the Governor’s Ball together, where they were seen both holding hands and locking lips. Forget being arm candy — Nina got to be the kissing partner that night!

September 2011: Fine Dining

Pretty soon, the rate of romantic date sightings of the pair began to increase, especially within the Atlanta scene. The way to a man’s heart is through his… well, you know.

January 2012: No Proposal

It didn’t take long for the story of Nina and Ian’s supposed off-screen relationship to get stretched by the tabloids. In Touch first reported a story that Ian had proposed to Nina over the holidays and that she refused him, but Us Weekly dispelled that rumor altogether. With the denial of the proposal story came a seeming confirmation that the two were indeed a very happy couple in another Us story entitled “Why We Love Each Other.” However, the two later backtracked on the couple talk. “We haven’t told anyone anything," Nina insisted to Nylon. (More on that later.)

January 2012: People’s Choice Not to Get Engaged

Following the big “no proposal” news, Nina and Ian attended the 2012 People's Choice Awards and commented on the situation. Contending that if there’d been a proposal, there would’ve been a ring on her finger, Nina then told Access Hollywood, “I’m a career woman and a young, very driven woman and I’ve got a lot I have to accomplish before I settle down and have kids and do any of that.” Ian added his own two cents, saying “If it were true, I would admit to it, ‘cause getting turned down builds character!”

January 2012: Not Kissing and Telling

In an interview for Nylon’s February 2012 issue, Nina put a few highly-cited quotes from the Us Weekly article into perspective. Ian had been quoted by Us praising Nina for her ability to “experience and appreciate everything around her, and chuckle and enjoy it,” while Nina lauded Ian for being “a glass-half-full kind of guy.” To Nylon, though, she said that she and her TVD co-stars who participated in the interview were asked several questions about each other and that those responses were cherry-picked from the innocuous “What do you love about your co-stars?” pool. She also added the telling statement, “We haven’t told anyone anything.”

February 2012: Academy Awards After-Party Action

During Hollywood’s biggest night, Nina and Ian ditched their previous efforts to stay below the radar during Elton John’s Oscar-viewing Party and shared some personal space — and dance moves — with each other for all to see.

April 2012: Fifty Shades of Ian

Ian Somerhalder has long been a favorite for the role of Christian Grey for the Fifty Shades of Grey book-to-film adaptation, but in an interview with On Air With Ryan Seacrest, Ian indicated he’d rather keep himself out of trouble and keep a proverbially “happy home” than to show any interest in who’d star opposite him for the female role of Anastasia Steele. Probably a good call, Ian!

April 2012: Coachella Kisses

Coachella Round Two! This year, the couple didn’t hold back and were photographed sharing sweet smooches during the show.

May 2012: Big Affection in the Big Apple

What a difference a year makes. Whereas the year before fans were still “are they or aren’t they”-ing themselves over Nina stepping out with Ian’s hat on her head, by May of this year they were seen prancing around New York City together, unabashedly holding hands and both wearing matchy hats!

September 2012: Nina Goes Public

As the Seventeen cover girl for October, Nina gave a lengthy interview to the magazine. She admitted, “The first time I was on the cover of Seventeen, the cover line said 'Nina: Why she wouldn’t date any of her co-stars.' And then cut to two years later,” Nina told the magazine. “It's funny that I said that, but you know what? It was honestly what I believed at the time. I didn’t want to be dating one of my co-stars — my goal on the show was to be professional. But sometimes you can’t help who you have a connection with, and you can only fight it for so long — which I did for a really, really long time.”

December 2012: China Bound

After spending their holidays together, Ian and Nina took a trip to China together. While it was mostly business, we’re sure they got in some cozy alone-time, too.

January 2013: Making Eyes at the Critics’ Choice

In January 2013, Ian and Nina were so in love that they only had eyes for each other at the Critics’ Choice Awards, according to onlookers. “Seriously, they spent most of the evening gazing into each other’s eyes. They’re utterly smitten,” said one.
