VICTORIA BECKHAM's popped four kids out, now it looks like her wonderful husband DAVID is taking his turn. Either that, or he's been spending too much time in Hooters (eating, of course) and piled on some pounds. However, I am reliably told he was pretending to be up the duff to make his sons laugh. Dishy Dave said recently he wants to add to their brood with a fifth child - and here he is trying it for size by putting something resembling a cushion up his Tshirt and sticking out his usually perfect abs. Becks, 36, was at Malibu beach with sons BROOKLYN, 12, ROMEO, eight, and CRUZ, six, while wife Posh, 37, was at home with baby HARPER.
