No Doubt singer steps out with her tiny baby bump

Gwen Stefani's baby bump is starting to show!

The No Doubt singer and fashion designer stepped out for a friend's baby shower with son Zuma in Yorba Linda, Calif., on Saturday.

Donning black leggings and a gray tank dress, the mother to two sons sported a barely there baby bump along with black chain pumps and sunglasses.

A source confirmed to E! News earlier this month that the singer and her husband, Gavin Rossdale, were expecting their 3rd child together.

The couple are proud parents to 7-year-old Kingston and 5-year-old Zuma.

We're not going to lie, we're hoping for a girl!
