As the two actresses posed for a cute pic backstage at the Teen Choice Awards Sunday, Kellan Lutz made sure to photobomb them while they were at it, stepping in the middle of them in the background and giving a pretty hilarious expression.
Right before they snapped the pic, the Hercules star and Nina hit the stage together to present the award for Choice Movie Actress, Action/Adventure, which went to Shailene.
Before the Divergent star hit the stage to snag her surfboard, Kellan and the Vampire Diaries star joked about keeping their distance from each other on stage to make sure they didn't start any dating rumors (Nina has been linked to just about everyone lately).
Kellan even joked on Twitter afterwards that he set a "5 feet radius rule" while they were on stage so they didn't have to stand close to each other.
Just a couple of weeks ago, reports flew that Nina was kissing and flirting with several stars at a couple of Comic-Con bashes. Nina later laughed that off by posting a shot of herself with "four more" possible boyfriends.
"Apparently I have SOOOO many boyfriends. Here's four more. I'm so busy. #tabloidsillyness," Nina captioned an Instagram shot, which showed her standing with a big grin on her face as four guys – fellow Vampire Diaries actors Steven R. McQueen, Zach Roerig, Joseph Morgan and Matt Davis all gave their best sexy smiles in the background.
