“Silver Linings Playbook” star Bradley Cooper got ladies spinning out of control at the SoulCycle studio in TriBeCa yesterday morning. Cooper showed up at the 7:30 class for an early workout. “He was trying to be incognito and wore a long-sleeved shirt for most of the ride,” an onlooker tells us. However, Cooper ripped off his shirt near the end of class, causing a ruckus among the mostly female riders. “Girls were literally falling off their bikes,” said our source. “At the end of the class, a few fans had the guts to go up to him, and he was super gracious. He introduced himself, shook their hands and even congratulated the girls on a great class.”
