Brian Friedman Gushes about "HIAM"

After her stop at the recording studio Thursday in L.A., Britney dropped by the Basement dance studio to brush up on her new moves.

Brit's choreographer, Brian Friedman, spoke with MTV about the details of the moves Britney's learning for her song Hold It Against Me.

"This is a dance video. Rehearsals can get pretty rough," the choreographer said. "We're playing it safe, we're not trying to kill ourselves yet, but as the video comes closer and closer, we'll definitely be hurting our backs. There was a moment while we were rehearsing where I showed Britney a section and it was something I really wanted her to do, and she freaked out. ... It's crazy when you first see something like that, how overwhelming it can be, especially when you haven't been in the [dance] studio for a year."

Brian and Britney have worked together numerous times over the years, including for her "Overprotected Dark Child Remix" music video and "Toxic."

"From then on, we became friends and she is fun to work with," he gushed. "She's a Southern girl - she's all about having fun and laughing and cracking jokes. I think you can expect the unexpected from Britney. She is taking risks when it comes to fashion, when it comes to choreography, when it comes to this music - she's grown up so much, and she's pushing 30 years old soon, so she's a strong independent woman and I think she wants to show that."
