Demi Lovato and Eminem are not two names often tied together. But the pop singer recently shared that she'd like to change that, saying she'd love to hit the studio with the legendary rapper.

"Hopefully, I can work with Eminem," the singer told E! News about her dream collaboration. "He's my favorite rapper, so anything with him would be amazing."

Hip-hop fans might be surprised to hear about Lovato's love for the genre, but Lovatics are more familiar with it. She made headlines last fall with her gut-busting cover of "How to Love" by Lil Wayne. When she spoke to MTV News about the deeply personal track, she fessed up about her love for the rapper and his song.

"I just loved the way that Lil Wayne took a risk doing the song 'How to Love,' and when I really listened to it, it's such a great song," she said. "It has such a deep meaning to it and I wanted to perform that, and I put a little spin on it and tried to make it a little more empowering. And I think it fit with the platform and the message that I have with my fans."

Lovato's one of many artists crossing over between pop and hip-hop. Taylor Swift was at the forefront of the trend in 2011, hitting the stage with the likes of T.I. and Nicki Minaj. And Justin Bieber said he'll likely work with Drake and Kanye West on his 2012 release, Believe. So it seems this trend isn't going away anytime soon.
