Drew Barrymore is pregnant with her second child.

The '50 First Dates' actress is reportedly expecting a baby with her husband Will Kopelman, multiple sources have confirmed to Us Weekly.

The couple - who tied the knot in June 2012 - already have a 13-month-old daughter, Olive.

Rumours have been circulating in recent days that Drew could be pregnant again after she was spotted in a series of loose-fitting outfits.

The 38-year-old star donned a long, flowing dress to the LACMA Art+Film Gala honouring Martin Scorcese and David Hockney over the weekend, which appeared to conceal her growing baby bump.

Drew has been vocal about her desire to expand her family in the past, explaining she wanted to give Olive a sibling close to her own age so she didn't feel lonely.

She recently said: ''I was an only child and it was lonely. Some people love it and thrive on the independence but I want my kids to have other kids around.

''Maybe two kids so they can run around life together, roll their eyes at their parents together. So however that's going to come about, it's gonna happen!''
