Gwen Stefani's pregnancy baby bump finally made its first appearance in 2013! The "No Doubt" singer debuted her growing belly in a grey tank dress, confirming that she is expecting her third child with Gavin Rossdale. 

According to US Weekly, the "No Doubt" signer, 43, showed off her growing baby bump while attending a friend's baby shower with her 5-year-old son, Zuma in Yorba Linda, Calif. on Saturday.

The blonde songbird was wearing a tight dress and black bra, revealing her protruding belly. The singer paired the look with black leggings and high heels, and her signature red lipstick. Her blonde hair was down and her skin glowed, reported US.

For the first time since pregnancy rumors began surrounding Stefani, cameras caught her flaunting her mid-section instead of hiding it again with baggy clothes. 

A source told US that the L.A.M.B designer and her husband, Rossdale were expecting another child together.

"It's very new and they just found out," the insider told US earlier this month. "They're excited!"

Stefani has been hush hush about the baby news since it was first reported a few weeks ago. On Sept. 5, Stefani covered up her pregnancy curves in very baggy khaki pants and a draped, off-the-shoulder top. 

The performer also wore a loose-fitting black tank top while out with her son, Zuma on Sept. 11.

At this point, it's unclear how far along Stefani is in her pregnancy or whether the baby will be a boy or girl. But the new addition will join older brothers, Zuma and the couple oldest child, Kingston, 7.
