On Wednesday night at Los Angeles’ PINZ bowling alley, Christ Brown allegedly  exploded on a parking attendant over a $10 valet charge. The 23-year-old, who had been at the venue for a charity event, was furious he had to pay the fee.

According to PINZ’s Facebook page, the bowling alley was hosting a “Stars and Strikes” celebrity bowling and poker event on behalf of the youth-centered charity, A Place Called Home.

The Wanted, Pete Wentz, Patrick Stump, Nick Cannon and will.i.am were all expected to be in attendance. Brown was not featured on the billing.

Earlier Wednesday afternoon, Brown reportedly had an “altercation” with his bodyguard, Big Pat.
