Victoria Beckham pregnant with fifth child?

Mother of four Victoria Beckham has sparked a pregnancy riddle after avoiding alcohol and admitting strange food fads.

The number seven is reportedly the Beckham clan's lucky number - footballer David wore the numbered shirt during his reign at Manchester United, and the couple named their daughter Harper Seven - so a fifth child would take the Beckham family count up to their magic number.

"I'd never say never about another baby," fashion designer Victoria, 38, was recently quoted as saying in an interview, and now she's fuelled the reproductive fire by dropping hints that her current unruly brood might become even more unruly next year.

An "insider" told Heat magazine that while Victoria was in London to participate in the Olympics Closing Ceremony, she was "talking about having some strange food fads and she didn't drink at all, not even to celebrate after performing at the Olympics."

Said gossip went on to divulge that Victoria's behaviour "led to some of her friends asking outright if she was pregnant and she just smiled in response."

David and Victoria Beckham, who are based in Los Angeles, already have sons Brooklyn,13; Romeo , 10; Cruz, 7 and daughter Harper, 15 months.

"We've always said we'd love a big family and five was a number," said LA Galaxy and H&M pin-up Beckham recently. "If we're lucky enough, then we hope to have one more."
