Friedman 'to show off new side of Spears'

Brian Friedman has claimed that he brings out a different, more aggressive side to Britney Spears when choreographing her music videos and performances.

Friedman, who regularly worked as Spears's choreographer early on in her career, reunited with the singer recently to work on the video for 'Hold It Against Me'.

"I haven't been with Britney in five years on a project, so it was exciting to be back with her," Friedman told MTV News, before explaining that he was enjoying giving Spears a challenge.

"It's not necessarily that she hasn't been dancing, it hasn't been what I get from her, and what I seem to get from her is this tigress quality," Friedman continued. "And she prowls. She really dominates when she does my choreography."

The video was directed by regular Lady GaGa collaborator Jonas Åkerlund, but has yet to receive an official air date.
