Gene Simmons couldn’t rock and roll all night.
The KISS frontman, 66, co-hosted a party on Saturday night at pal Rohan Oza’s sprawling LA mansion to raise money for a children’s charity.
Forgoing black-and-white stage makeup, the rocker surprised the crowd — including Randy Jackson and Maria Menounos — with a private concert until uniformed Beverly Hills police showed up to shut down the raucous sounds.
“The sound from Gene’s performance traveled all over Beverly Hills,” a source told Page Six. “The cops showed up because of the noise.”
Known for throwing exclusive parties in Tinseltown and NYC, venture capitalist Oza didn’t let a visit from the 5-0 end the glittering night — which benefited the Children Matter Foundation, an organization focused on improving the lives of kids around the globe.
“Gene put down the guitar, but the party continued with a DJ,” added the source.
This wasn’t the first time Simmons has rocked a charity event benefiting kids. Earlier this year, the bassist joined Johnny Depp for an impromptu number at a MendingKids.org party in LA.
