Are Selena Gomez and Leighton Meester frenemies?!

Well, not exactly.

But the duo did talk about how they managed to hate on each other for their recent flick Monte Carlo and that not knowing each other beforehand helped.

"When we first met, we obviously didn't know each other and we shot all the beginning stuff in the movie so it was easy to maybe not like her because towards the end of the movie it would've been really hard," Gomez told E! News at the film's L.A. junket.

Aw, isn't that sweet?!

Glee's Cory Monteith is also in the film and said that days on set with those two starlets were always fun. Then he goes on to melt our hearts when he answers a question about whether or not he would travel the world for that special someone.

"I really hope one day I can, you know?" he said. [Swoon...] "I'm still waiting to meet that girl. I think it'd be really cool if I could."
