Britney Spears: On A Fitness Kick!

Britney Spears leaves an office building after having a meeting on Thursday (March 28) in Thousand Oaks, Calif.

The 31-year-old entertainer tried to cover her face with a hot pink item as she headed to her car.

“She’s looking so great because she has been on a total fitness and workout kick recently,” a source recently told E! about Brit‘s fab look. “She’s all about it. She’s been feeling really motivated and happy and it shows.”
