Jennifer Lopez -- Moving From The Block ... Cuz It's Too Damn Big

Exclusive Details
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.
