Jennifer Lopez loves her beautiful big ass, but not her beautiful big ass house ... because she's unloading it.
JLo is selling her 3+ acre, 17,000 square-foot Hidden Hills estate, because it's just ridiculously big for her small family.
We're told Jennifer and her 2 kids have their sights set on Malibu ... a smaller house with a better view.
She'll definitely have the cash to buy something new. She purchased the Hidden Hills mansion for $8.2 mil in 2010 and is asking for a cool $17 MILLION.
No word yet if Casper is included in the sale.
