Bowlmor Lanes' 70th Anniversary Party

Michael Phelps and Benji Madden

Bowlmor Lanes celebrated seven glorious decades of ten-pin with an eclectically star-studded event, hosted by golden Olympian Michael Phelps. (Although you'd think his 15 well-deserved minutes of public adoration would be coming to an affectionate close, the crowd lost its mind when he showed up.) Who else was there? Well, Aubrey O'Day and her Obama-loving dog, the Obama girl herself, Cory Kennedy, Benji Madden (above), Victoria's Secret model Selita Ebanks, Ben Bailey, Donny Klang and other Olympic athletes. Is bowling an Olympic event? No. Should it be? Maybe.
