PICKING PALTROW: Tracy Anderson and David Babaii would be hard-pressed to find a better champion of their efforts than Gwyneth Paltrow, who showed off her assets in a mini Victoria Beckham dress Thursday evening for the opening of Anderson’s flagship fitness studio in the Los Angeles neighborhood Brentwood. “I think Gwyneth now looks hotter than she did 10 years ago,” said hairstylist Babaii, whose namesake four-chair blowout bar is housed inside the flagship. “She’s reversing the clock.”

Babaii and Anderson are relying on Paltrow’s brains as much as her beauty. Paltrow is Anderson’s business partner, and Babaii said she’s heavily involved in his new hair-care line, which launches at the studio before being introduced with 45 products priced roughly from $19 to $25 with Paltrow’s lifestyle newsletter Goop in about three months.

Paltrow certainly has the energy to work as well as work out. Babaii, who has lost 100 pounds using Anderson’s methods, can’t keep up with Paltrow. When he’s exercising with her, he said, “I’m like, ‘I’m done. I need a juice,’ but she says, ‘You got to do more. You got to do more.’”
