Gene Simmons is out with the old, and in with the VERY new after plunking down $10.5 million on a stunning modern mansion in the Hills of Beverly.
We've learned the KISS star actually got something of a deal for the 4-bed, 5-bath crib with close to 8,000 square feet of living space. The deal closed today, so Gene's personal belongings probably haven't even made it through the front door yet.
As for the home ... it's about as modern-looking as they come, with a pool complete with LED lighting, a home theater, built-in art installation and wine cellar fit to hold enough booze to get a small village wasted.
Simmons has been quite the real estate aficionado as of late ... he recently sold his long-time Beverly Hills home for $16 million and just listed his Vegas crib for $15 million.
Gene scored big on his most recent purchase, the home was first listed at $11.5 million ... so the $10.5 million Simmons paid to the former owner -- a billionaire Swiss steel magnate -- ain't too bad.
Celeb real estate agent Tomer Fridman -- who reps the Kardashians on almost every real estate transaction they make -- repped the seller. He's with Compass. Gene was represented by Lisa Young ... also at Compass.
