Gwen Stefani Pregnant: "Hollaback Girl" Singer Debuts Baby Bump with Husband Gavin Rossdale

Gwen Stefani is pregnant! The "Hollaback Girl" is expecting her third baby with husband Gavin Rossdale. Stefani, who is way too cool of a chick to be 44 years old, debuted her growing baby bump at the Wallis Annenberg Center for The Performing Art Inaugural Gala in Beverly Hills Thursday night.

Back in September Stefani revealed she was thinking about being pregnant again soon.

"I really, really, really wanted one about two years ago. And it didn't really work out. So...I feel good with what we've got. Everything works out how it should. You can't plan anything, right? You can try."

That was just last month and there is already a baby in the oven. Apparently she's been pregnant for some time now.

Stefani and her husband Rossdale shared a table with Demi Moore and was even seen talking to Josh Duhamel, who just welcomed his son Axl with Fergie.

Stefani and Rossdale recently celebrated out 11-year wedding anniversary and just announced her upcoming nail polish line and her L.A.M.B. spring 2014 collection which was just debuted at New York's Fashion Week.

Stefani has yet to publicly comment on her pregnancy.
