Explore the $50 Million LA Mega-Home, Former Residence of Prince, Featuring Its Own Subterranean Entertainment Complex and Spa.

This palatial $50 million Mediterranean-style estate in Bel Air, California, where Prince once lived and the Season 8 cast of “American Idol” stayed, has a lavish secret buried under the lawn — it’s own multi-level, subterranean entertainment complex.

Superbroker Aaron Kirman and his colleague Tay Hasselhoff gave CNBC an exclusive tour of the 36,000-square-foot mansion for an upcoming episode of CNBC’s “Secret Lives of the Super Rich.”

The 16,000-square-foot main residence has 20 bathrooms and eight bedrooms.

Once inside, down two flights of stairs, the estate’s buried secret is revealed: It’s the entrance to the subterranean entertainment complex.

“You have three levels of pure party perfection,” Kirman tells CNBC.

The spa

That “pure party perfection” starts with the complex’s spa.

The main attraction is a resort-sized swimming pool.

“When Prince rented this house, he used to throw the most amazing parties in this room. He would literally cover the pool with glass… and have these amazing jam sessions,” Kirman explains.
