Gwen Stefani debuted her tiny baby bump visibly for the first time on Saturday, after previously trying to attempt to hide it under baggy clothes. 

The 43-year-old showed off her growing pregnant stomach with 5-year-old son, Zuma while attending a friend's baby shower in Calif.

Stefani dressed her bump a tight gray tank dress with matching black leggings. She also wore black high heels, shades and her trademark red lipstick. 

The "No Doubt" singer looked absolutely gorgeous as she also wore her blond hair down her back.

This will be the third child for Stefani and husband, Gavin Rossdale. The couple already has two sons, Zuma and 7-year-old Kingston. 

"[Gwen] and Gavin couldn't be happier" about their exciting news, a source close to the couple told In Touch Weekly on Sept. 4. "She's in the early stages, and she's having a hard time with morning sickness."

At the time the news broke, a source said the couple wanted to keep the news under wraps, as Stefani was in her early stages of pregnancy.

"It's very new and they just found out," the source said, adding, "they're excited."

In a September 2012 interview with Marie Claire magazine, Stefani also revealed that she and her husband had tried for a third child in 2010, but it didnt work out.

"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," she said.
