David and Victoria BeckhamDavid and Victoria BeckhamThey've got three kids already...

But could sprog number four be on the way for the Beckhams?

They're certainly putting in the practice, it seems.

Appearing on the Ellen DeGeneres show, David Beckham spilled all on his and Victoria's plans for a bigger brood.

When questioned about the possibility of more kids, Becks - whose three sons are Brooklyn, Romeo and Cruz - replied that he and VB "were working on it", adding: "We're very family orientated, so we've always wanted a big family, which was weird because when we first got together we never even discussed how many we wanted.

"But we love kids, so it's worked out perfect."

And it sounds like things are already going in the right direction for more children - when host Ellen asked Dave whether he and Vic were comfortable being naked, he replied:

"Around the house we are - yeah."

Wowsers, that's frankness for you.

We'll be keeping a close eye on Vic's stomach from now on - she's on official baby watch.
