What Went Wrong | Kenny Chesney, Renee Zellweger
On Sept. 16, the day after the sudden end of her four-month marriage to Kenny Chesney became public, Renée Zellweger was in New York, where she turned up at a steakhouse in the Hamptons. She requested a table for one, kicked off her sandals and quietly dined on salmon and steamed spinach before leaving a $100 tip. "She didn't act sad or upset," says an observer. "She was so sweet."

Two days later, at the Farm Aid concert in Tinley Park, Ill., her soon-to-be ex – wearing his signature second-skin Levi's, a Stetson pulled low over his eyes – also put his best boot forward, gamely singing, dancing and air-fiddling his way through his hits. "He's a professional," says Faith Hill; she and her husband, Tim McGraw, are longtime friends of Chesney's. "You just have to go on," she says, adding, "It's gonna be a rough couple of weeks. But I think everyone's gonna be okay."
