Mindless Behavior is taking over the R&B mainstream right now.

The teen group has landed their first No. 1 album on the Billboard Hip-Hop/R&B album charts with their sophomore effort, 'All Around the World.'

Princeton, Prodigy, Ray Ray and Roc Royal sold 37,000 copies of their album in its first week of release, beating the first-week sales of their debut album, '#1 Girl' -- they sold 36,000 units of the effort.

The LP was accompanied by a roc-documentary by the same name, which gives a behind-the-scenes look at the four young ones' musical journey. The film hit theaters on March 15.

In other Hip-Hop/R&B Chart news, Rihanna's 'Unapologetic' has climbed back to the No. 2 position while Macklemore and Ryan Lewis' 'The Heist' falls to No. 3.
