No Doubt singer Gwen Stefani is reportedly pregnant with her third child. The fabulous frontwoman and fashion designer has two sons with hubby, Bush singer Gavin Rossdale. She is 43.

A source told InTouch that Stefani and Rossdale "couldn't be happier" about welcoming their third child and about expanding their brood.

So far, there has been no confirmation about Stefani's condition and status from her camp or from the singer herself. If she is indeed preggers, this could slow down the process on a new No Doubt platter...or not.

The insider said, "She’s just trying to focus on resting right now. She wants to make sure that all is well with the baby."

Stefani's firstborn son Kingston is 7 and his little brother Zuma is 5. Can you imagine if Stefani finally had a little girl who would inherit that enviable closet and perhaps mommy's fashion sense?

Kingston and Zuma are precious, grabbing the best DNA from both mommy and daddy. They are two of the most well-dressed Hollywood tots we've ever seen. But could you imagine Gwen with a girl?

If Gwen Stefani is indeed expecting, PopCrush sends her our very best!
