If there's one musical collaboration fans have been begging for, it's the combination of Selena Gomez and Taylor Swift .

Sure they've posed on red carpets together. And yes, they've appeared in the same music videos. But is there any chance the pop superstars will make a song together?

"Oh, I don't know. I mean, eventually, right?" Selena told E! News at the Sundance Film Festival. "She's my best friend. We'll see."

While it may not be a flat-out yes, it certainly isn't a denial either. Perhaps we just need to give it time for Selena who has a few big-screen projects on the horizon.

On Friday evening, the actress was able to support her upcoming film The Revised Fundamentals of Caregiving. It's a project that impressed her from the very beginning.

"I completely fell in love with the vulnerability and the angst that [my character] had. I don't know what that says about me but I responded to it," she shared with E! News. "When I met [director Rob Burnett], I don't think he would of put somebody like me in that character but I auditioned three times, I fought for it and I knew that it was something that would mean a lot."

She continued, "What the story represents is really touching. It's about three broken people and everybody's dealing with stuff and I think people can relate to that so I'm excited."
