It’s been quite a week for Vampire Diaries star Nina Dobrev. Last night, she and on-screen flame Ian Somerhalder took home the People’s Choice Award for “Favorite On-Screen Chemistry.” And, today, she celebrates her 25th birthday with the people she loves!

“Happy Birthday @ninadobrev with @iansomerhalder @juliannehough @julieplec,” TVD executive producer Kevin Williamson tweeted, along with a seriously adorable picture of the birthday girl celebrating with Ian and best friend Julianne Hough. In the pic, Nina is holding a birthday cake while Ian and Julianne cuddle up close to her. The best part? These three have the biggest smiles ever on their faces.

Ian was one of the first to wish Nina happy birthday on Twitter, making us instantly swoon. These two are officially broken up, but they still seem super close and continue to inspire reports that they’re still hooking up. Either way, we love the love!

Nina’s gal pal Julianne got in on the online declarations of love, too. Earlier today, she posted a snapshot of the two besties hugging while Nina proudly displays her birthday cake: “Happy Birthday my beautiful @ninadobrev you are kind, smart, adventurous, loving, honest, beautiful, mysterious, free, funny, and so on and so forth..... I am so lucky to call you my best friend! I love you so much... My sister! Happy birthday ya ol' fart!!! :) xoxo,” she captioned the pic.

Happy birthday, Nina! We hope you have a wonderful day and year. By the looks of it, you’re already off to a good start.

Isn’t this trio adorable? Hit the comments and send birthday wishes to Nina!
