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.
As for where Brit will be moving ... real estate sources tell us she and fiance Jason Trawick will be renting a house for the short term, until they find something they want to buy.
