Drew Barrymore is pregnant again

(UPI) -- Drew Barrymore is expecting her second child with husband Will Kopelman, the 38-year-old's rep told US Weekly Monday.

Though Barrymore has yet to comment on her second pregnancy, the actress wore a loose-fitting dress to Saturday's LACMA Art+Film Gala that could have easily concealed a growing baby bump.

Barrymore and Kopelman already have an 13-month-old daughter, Olive. The former Charlie's Angels store told Jay Leno last month that she was eager to give Olive a brother or sister "right away."

"I grew up as an only child, and although that really works for some people and for some parents that’s the way they want to do it…I want to be the Griswolds," Barrymore said.
