No...she's not at the latest premiere.

But she could be...

Gwen Stefani was spotted leaving Cedars-Sinai Medical Center in a sexy pair of skinny jeans and stilletos.

The 39-year-old singer, who gave her blonde bangs a mini-boost, couldn't hide her rockin' figure underneath a loose-fitting gray tank belted low on the hips.

No word on why the No Doubt singer was at the hospital.

But we did happen to catch that sly grin on her face....

Now that the group's summer tour is complete...could Gwen be going for baby number three?

We're not trying to stir the pot...

We're just sayin'...with cuties like Kingston and Zuma...would another Stefani spawn be so bad?
