Britney Spears Sells Home For Huge Price -- Will Move in With Fiance Jason Trawick

Britney Spears has sold her Beverly Hills estate ... TMZ has learned, but that's not the big thing. Get this ... it was listed at $2,995,000 and real estate sources tell us it sold for $4,253,000.

We're told Britney's people listed the house at a modest price, expecting multiple bids and possibly even a bidding frenzy. It looks like it worked out for them, because the price they accepted is more than a million over asking.

And it gets better ... because Britney is under a conservatorship in probate court, there will be a hearing on the sale next month, and anyone can come to court and overbid the accepted offer.

The house is in the Summit, an exclusive gated community -- and it's the house where Brit famously had a meltdown in 2008 ... when she was strapped to a stretcher and taken to a hospital.
