Yoga mama!

While Drew Barrymore waits for her baby to arrive, the actress is keeping busy by focusing on fitness. 

The 37-year-old actress was spotted leaving a yoga class in Los Angeles on Monday wearing sweats and carrying a yoga mat. Barrymore's growing baby bump was on full display as she made her way to her car with her hair in a bun and blocking the sun with cute heart-shaped sunglasses.

Barrymore married art consultant Will Kopelman, 35, on June 2 at the actress' Montecito, Calif. estate. The baby-to-be will be the newlyweds' first child.

Cameron Diaz threw her Charlie's Angels costar and best friend a baby shower at her home on Aug. 4 in Los Angeles. "Kids were jumping in a bouncy castle," a source told Us Weekly of the party.

The Big Miracle star admitted to Jay Leno on The Tonight Show in February that she hopes to have multiple children with Kopelman. "We'll start with one," she said. "See how it goes and if we could be so blessed . . . that would be wonderful."
