Are you ready for Katy Perry’s body roll?

Katy Perry and Juicy J turned up for charity last night. The two unlikely collaborators performed their new single “Dark Horse” for the “We Can Survive: Music For Life” charity concert in L.A.

During her set, Katy Perry belted out her inspirational track “Roar,” but when Juicy J emerged on stage, she turned up and showed out. Katy Perry channeled her inner “trippy” and debuted a seductive body roll for Juicy J.

In other KP news, the “Unconditionally” singer’s new album is projected to debut at number one on the music charts. Prism is projected to sell over 275,000 copies in its first week, which is a significant jump from her 2010 Teenage Dream album, which sold 192,000 copies in its first week.

Despite its mediocre debut, over the past three years, Teenage Dream has sold over 2.8 million copies in the U.S. alone. Katy’s Prism is currently available at a music retailer near you.
