George Clooney, Neil Diamond sing duet at Carousel of Hope Ball

George Clooney was the night’s honoree at the Carousel of Hope Ball in Los Angeles on Saturday night. And he was in such a good mood that Neil Diamond persuaded him to sing along on parts of “Sweet Caroline,” despite Clooney’s protests that he can’t carry a note even though he’s Rosemary Clooney’s nephew. Meanwhile, his girlfriend, Stacy Keibler, looked stunning in a Monique Lhuillier gown. The event — one of the biggest on the city’s fall social calendar — reportedly raised $2.5 million for the Barbara Davis Center for Childhood Diabetes. [Society News L.A.]

Lagerfeld goes further, denying saying it at all. [WWD] [The Cut]
