It might have something to do with her new beau, Austin Stowell, who she was reportedly spotted getting "touchy-feely" with at her Final Girls screening in Los Angeles Tuesday, according to Us Weekly.
Nina and Austin didn't pose for photos on the carpet (so they're still trying to keep things somewhat on the low), but the Whiplash hottie did stay close by while she smoldered for photogs in a cleavage-baring, red and white Monique Lhuillier dress. They were also holding hands, he was calling her 'babe' and had his arm around her waist at one point inside of the premiere (we are so loving this).
News first broke that the former Vampire Diaries star and Austin are dating after she brought him to her pal Jaime King's baby shower last weekend and called him her "boyfriend." Supposedly, Selena Gomez was the one that hooked them up.
So far, Nina and Austin have kept quiet on their relationship to the media, but, we love that this guy is making her happy. She certainly deserves it.
