Fresh from a weekend celebrating at Coachella, Paris Hilton was out in Hollywood last night. But this partying was for a good cause.
Paris, sister Nicky and her boyfriend, David Katzenberg, hit Lucky Strike Lanes to bowl for the Project A.L.S. benefit.
Seems the single life has been good for P's bowling skills: She tweeted that she got three strikes in a row.
Meanwhile, her ex-boyfriend Doug Reinhardt has been having his own run of good luck...
At Night Vision's Coachella Oasis last weekend, he was spotted sucking face with a brunette.
And on Monday night, Doug was back in L.A. leaving Industry with a mystery blonde.
But a source tells E! News that the burrito heir isn't looking for a new girlfriend right now.
"He's just having fun," says our source. "He doesn't have or want a new girlfriend."
