Victoria Beckham and David Beckham are still looking for a home in the U.S. - but don’t think they’ll overpay on their mortgage just because they’re famous!

The couple refuses to get screwed on a house whose price has been jacked up simply because the famous pair and her huge breasts are in the market.

“It’s pretty hard to keep identities secret when you are interested in multimillion-dollar mansions,” a source close to the Beckhams said.

“Once sellers find out who’s interested in buying, the prices immediately skyrocket. It’s ridiculous.”

As a result, says the source, “Victoria and David have still not decided on a house for when they move to L.A. They refuse to pay above the odds just because they are famous.”

In January it was announced that the David Beckham would move to California after the former English soccer captain, 31, signed a lucrative five-year deal with the L.A. Galaxy - which apparently exists.

Since then, Victoria Beckham, a.k.a. Posh Spice, 32, has made several trips to the west coast to check on possible homes for themselves and private schools for their sons Brooklyn, 8, Romeo, 4 and Cruz, 2.

Although schools have been narrowed down, the family is struggling to find a suitable mansion. Britney Spears is currently experiencing the same thing!

“They will definitely buy in or around Beverly Hills. It makes sense for them,” a pal says. “But they will not pay excess prices purely because of who they are. They’re careful with money.”

Reps for the couple were not immediately available for comment.

“They don’t want to get stuck in a bidding war. One mansion recently went up by millions as soon as the owner found out the Beckhams were interested,” says the source. “The problem is they need a big house.”

Doesn’t Tom Cruise have guest quarters or a pool house or something?

One thing’s for sure - wherever they land will be recorded for TV cameras, since Posh has signed to star in a six-part, NBC reality show that will coincide with the family’s move to L.A.

“They have a lot of work to do before David finishes playing soccer in Spain,” says the source. “Their house in Madrid needs to be sold before they move in July.”

Otherwise, they could get saddled with two mortgages. Which is a concern every relocating homeowner faces. No clue how they’d be able to afford that on his $50 million salary. Maybe with a bridge loan?
