Gwen StefaniGwen StefaniIs Gwen Stefani holding back?

Because there's an awful lot of chatter saying she is...

According to reports she's got a bubba in the oven.

And the news is spreading like wild fire.

The word on the baby block is that Gwen is 13 weeks preggers with bambino number two.

So Gwen, her hubby, Gavin Rossdale, and their wee laddie, Kingston, could be counting the days before their trio becomes a foursome.

A source told the Daily Mirror: "They found out at California's Cedars-Sinai hospital and couldn't wait to share the news with everyone."

You can be sure that we'll be keeping our ear to the ground to get some confirmation of the pitter-patter of tiny feet.
