David and Victoria have been spotted eyeing off multi-million dollar houses in west London with a view to moving back to the UK when David’s five-year football deal with LA Galaxy finishes later this year.

“They have been looking at houses over the past few months and the future is exciting as anything could happen,” a source told the UK’s Daily Mail.

“The thing they are most concerned about is giving the children stability. What is nice about being back in the UK is that they would be close to both their families again.”

The pair are also said to be planning a sibling for Brooklyn, 13, Romeo, 10, Cruz, 7, and 15-month-old Harper.

“Victoria is being very quiet about things. But she had never made it a secret that she didn’t see why she would stop after baby number four,” the source said.

“She loves having a big family and David has always said he would be thrilled if they had another child.”

The glamour couple and their family were back in the UK for the Olympics and both David and Posh were involved in the opening and closing ceremonies. In fact, it was Victoria’s strange behaviour following her performance with the Spice Girls that sparked rumours of another pregnancy.

“[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,” a source told Heat magazine.

When asked whether Victoria was expecting, her representative said: “She’s not pregnant as far as I know”.

But the couple, who welcomed Harper just last year, have never shied away from talking about more children.

“I’d never say never about another baby,” David said.

“We’ve always said we’d love a big family and five was a number. If we’re lucky enough, we hope to have one more.”

While Victoria is also keen for another kid, she recently spoke out about the pressures of running a successful fashion label and being a mum.

“I’m not going to lie about it, I’m tired. I’m really tired but I’m also very happy with my life. I’m basically just like any woman who’s working and has lots of children – it’s tough,” she told the Sunday Mirror.

“I’m not getting much sleep at all,” she said. “Harper’s not sleeping that great, and I’ve been taking Skype business calls throughout the night too because of the collections.”

If the pair do move back to the UK, where Victoria’s fashion headquarters are located, David will have to decide what he will do after retiring from professional football. He has already ruled out coaching and management positions.
