There's another one for Team Britney. Music director Wayne Isham has nothing but high praises for the troubled pop star as he tells what's it like to work with Britney Spears.

"On set, she was very professional, excited to work and beautiful as always. I was impressed with her focus as she choreographed the dance herself. Her endurance was remarkable, as we had a long day," the director, whose credits include videos for Madonna, 'N Sync, Metallica, and Faith Hill, says of the 26-year-old mother of two.

"She almost outlasted me, which is amazing! It was a pleasure to work with her again." Isham has directed her latest video, "Piece of Me" and her earlier "I'm Not a Girl, Not yet a Woman" video.

Meanwhile, reports are surfacing that Spears wants pal Sam Lufti to marry her. The "Toxic" singer has reportedly announced her marriage plans to lawyers and her ex, Kevin Federline. Her lawyers advised her to "at least get a pre-nup, but she didn't seem to be listening."

Spears has been seen constantly with Lufti since her divorce. Federline allegedly is against the union as he fears Lufti may lose temper with Spears and their children. "Kevin has seen Lufti lose his temper. We hear he swears a lot and makes very derogatory statements when he's alone with Brit," a source says.

"Kevin has forbidden Britney from having Sam around the boys. She'll lose custody if she allows Sam around then, Kevin will make sure of it."

Spears and Federline are currently involved in a custody battle for their children, Jayden James and Sean Preston.
