Kate Hudson: Bikini Babe in St. Tropez!

Kate Hudson shows off her post-baby body in a blue and white bikini on Monday (June 25) in St. Tropez, France.

The 33-year-old actress lounged on a luxury yacht with her almost 1-year-old son, Bingham, after doing some shopping earlier in the day.

Kate will be guest-starring on Glee when the Fox show returns this September.

She’ll be playing a “hard-ass New York Academy of the Dramatic Arts dance instructor, pitting her against new student Rachel [Lea Michele],” according to TV Guide.

“Dance is not Rachel‘s strong point, but as a freshman it’s a requirement class she has to take,” Lea shared. “It will put Rachel in a very vulnerable place, stuck with a teacher who doesn’t make it easy for her.”

FYI: Kate is using her aden + anais muslin swaddle!
