Let us blow ya mind.
Only, it wasn't Gwen who confirmed it, but her one-time collaborator and rapper mate Eve.
When asked during an interview with Live Nation today whether Gwen would be making an appearance at an upcoming performance in New York, Eve responded, 'Well, she's preggers! She's chilling...'
While that probably wasn't quite how Gwen envisaged the news breaking, we're just as thrilled to hear it. The baby will her third with muso hubby Gavin Rossdale and a younger sibling for sons Kingston and Zuma. Plus, the unexpected announcement puts her in pretty fabulous A-list company - remember when Jack Black famously let slip that Angelina Jolie was pregnant with her twins during an interview at the Cannes Film Festival in 2008?
