Check out Lady Gaga $25 Million mansion with a secret 'Bat-cave' In Malibu! [Photos]

The mansion that Lady Gaga just bought in is remarkably... beige.
But it comes with her own personal "Batcave" -- accessed through a secret passage in the living room -- that's equipped with an authentic 1960s bowling alley and two basketball free-throw machines. Not that we'd necessarily have pegged her as a bowler. continue after the cut..............

She also gets an 800-bottle wine cellar, a lighted outdoor bocce ball court, a saltwater swimming pool (other than the Pacific Ocean across the street at Zuma Beach), and a master suite with his-and-hers bathrooms and walk-in closets in more than 10,000 square feet of living space. The master bath designated "hers" has a soaking tub, "his" a rain shower and steam shower; both have bidets and heated stone floors. "His" closet also contains a safe room, with a Crestron security system protecting the entire estate.

She bought the property from Dan Romanelli, a Warner Bros. executive who founded the studio's consumer products division. "Batman was something that really helped build my division," he told the Wall Street Journal, and he wanted a "Batcave" for his vintage toys and arcade games, both for his grandchildren and "older people like myself who feel like kids."

He paid $2 million for the land -- nearly 6 acres -- in 2002, and built the house in 2006. "The estate still feels and looks brand new – a testament to its design and construction," the recent Agency listing boasted.

He and his wife keep horses, too, so the property has a riding arena and trails, plus grazing pastures.

Lady Gaga paid $23 million for it, according to the Los Angeles Times. It was listed with the Agency at $25 million.
