It's "Hannah Montana" Week here at MTV News! Check back here every day leading up to the flick's April 10 opening for exclusive Miley Cyrus interviews, videos and more.

Self-proclaimed BFFs Miley Cyrus and Taylor Swift already teamed up onstage at the Grammy Awards earlier this year. Now, the powerful teens are ready to take on Hollywood together.

It probably wasn't hard to convince Taylor to make a guest appearance in Miley's "Hannah Montana: The Movie," considering their bond.

"Yeah, we've known each other for a long time," Miley Cyrus told MTV News. Not only do the girls share experiences as teen stars, but they also both happen to be former girlfriends of Jonas Brothers. Not that they dwelled on their love lives on the set of the film. According to Cyrus, they were all about business on the day Swift shot her cameo.

"It was pretty pro, because we were all working and stuff, but we had fun," Cyrus added. "We actually didn't get to hang out that much while we shot because she was in such a quick scene, but it was fun to have her on set. She's cool."

As much as she enjoys collaborating with Swift, Cyrus said she's not going to cross over from pop music to country anytime soon. "Maybe one day, but I'll leave that to pros," she said. "I don't know what I want to do."

Swift, who also has a song, "Crazier," on the movie's soundtrack, had a great experience on her friend's set. "Miley Cyrus is awesome. I love her so much," she said on the "Today" show last summer. "She is so incredibly funny and sweet!

"I'm just really excited about it, because it's really cool when some of my little fans will come up with a 'Hannah Montana' shirt on," she said. "I want to be like, 'Guess what? I get to be in that movie with her!' "
