Nina Dobrev: I fought my connection with Ian Somerhalder for ‘a really, really long time’

Nina Dobrev, the cover girl for the October issue of Seventeen magazine, has been caught in a lie ... well, a sort of lie. Back in 2010, the 23-year-old star of "The Vampire Diaries" was pictured on the cover of the same magazine with a headline that hasn't exactly proven to be true. "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," says Dobrev, who has, in fact, been dating her sexy co-star Ian Somerhalder since a few months after that headline was printed. "And then cut to two years later ... 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."

At the same time she's been cozying up to Somerhalder, Dobrev has also forged a strong bond with the women who work on her show. They even regularly get together away from the set. "Girls weekend with the 'Vampire Diaries' girls has become a big deal!" Dobrev reveals. "It's our quality time. It's so much fun to unload and not feel guilty complaining or talking about your insecurities or bonding over things that you thought [you] were on your own about. When we get there, we go to dinner or cook dinner together, watch movies, lie on the beach and take tons of pictures. This year, we went to Disney World — I wanted to have funnel cake and pop, and just be immature with my girls. I think the most important thing about doing a girls' weekend, or spending time with your friends whenever, is that even though you're growing up, you should never stop having fun or getting excited about things!"

Dobrev, who stars in the upcoming Emma Watson movie "The Perks of Being a Wallflower," has a suggestion for what the gal pals should do the next time. "I want to go to Harry Potter land!" she says. "I actually should text Emma Watson to see if she can hook us up with a backstage pass or something. That's the perk of doing a movie with Emma called 'The Perks of Being A Wallflower.'"
