Update:

As of September 25, 2013, Nina Dobrev and Derek Hough are officially dating! The Vampire Diaries starlet and Dancing With the Stars pro haven't publicly said they're together, but a source close to Nina tell Wetpaint Entertainment exclusively that "they've been hanging out more on a one-on-one basis lately" and "recently started dating"! However, they're not jumping the gun and getting too serious — the source adds they're "having fun together for now." We're just glad our girl is happy.

A few other reports say they started seeing each other in August and are "somewhat serious" now; in fact, they've "fallen head-over-heels" for each other and Derek is reportedly quite smitten! Aww. Nina recently said she doesn't want to rush into anything, so we expect these besties-turned-lovers to keep things fun and simple.

Update (September 20, 2013):

While Nina and Derek are supposedly just friends, we have reason to believe their friendship may have transformed into something more. In a Instagram video shot by a fan on September 8, Nina and Derek can clearly be seen holding hands while attending a performance at the Roosevelt Hotel. That is, they were holding hands until a man came up and whispered something in their ears, after which they promptly dropped their arms to their sides.

Now, we’re not saying Nina and Derek are in full-on relationship mode, but we don’t know a ton of girls who hold hands with their single, straight friends like that. We'll just have to wait and see!

Original story (August 19, 2013):

Since breaking up with Ian Somerhalder back in early May, Nina Dobrev has been taking advantage of her single lady status. The Vampire Diaries actress has spent the summer traveling the world and partying it up with her fellow single friends

However, despite Nina saying she’s in “no rush” to start dating again, a recent report states that her pal Julianne Hough is attempting to set her up.

According to Star magazine, Julianne would love to see Nina get together with her brother, Dancing With the Stars pro Derek Hough.

Julianne is “very protective of Nina and doesn’t want to see her with a loser,” Star writes. And since she and Derek are incredibly close, Julianne’s “super picky” about who he dates.

While it’s true that Nina and Derek have been spending a lot of time together — the duo recently attended Lollapalooza in Chicago, where they supposedly looked “really into each other” — a rep for the star insists the two are “just friends.”

In fact, Nina and Derek have been friends for quite some time. Back in January, the duo were photographed at the Dior Dinner alongside Nina’s then-BF, Ian. Since then, Derek has been spotted hitting the town with a pretty blonde mystery gal.
