Well, there can be no doubt about it now: Gwen Stefani is definitely preggers!

The No Doubt frontwoman showed off her baby bump last night (Oct. 17) at the Wallis Annenberg Center for the Performing Arts Inaugural Gala in Beverly Hills. It was her first red-carpet appearance since word broke last month that she and hubby Gavin Rossdale were indeed expecting their third child together. Gwen, 44, and the Bush singer, 47, already have two sons, 7-year-old Kingston and 5-year-old Zuma.

Dressed elegantly in a floor-length silver Ferragamo dress that was covered in fringe, Stefani smiled for the cameras -- and even held her baby bump in one pic! Inside the event, she and Rossdale with spotted hanging out with friends including Nicole Richie, Courteney Cox, Demi Moore, Josh Duhamel, Rachel Zoe and Jennifer Meyer, aka Mrs. Tobey Maguire.
