Before Stacy Keibler, before Elisabetta Canalis, there was . . . Carole Radziwill?
On Monday's episode of Real Housewives of New York City, the new Bravo star's supposed A-list dating past came out of the woodwork during the girls' trip to St. Barth's.
As the 48-year-old author and memoirist showed off her sexy bod in a tiny bikini on the beach, an impressed Sonja Morgan quipped: "“Look at the a** on Carole . . . No wonder Clooney did her for a year."
Radziwill addressed the intriguing name drop on Twitter Monday night: "I don't kiss and tell but if I did tell I'd say Clooney was a very good kisser . . . But I"m not saying......just saying."
No other details have been revealed about her supposed romance with Clooney, now 50 and dating Stacy Keibler for a year.
For her part, the What Remains author is now casually dating Aerosmith rocker Russ Irwin. She is the widow of Anthony Radziwill -- a Polish prince and Jacqueline Kennedy Onassis' nephew -- her husband of five years, who died in 1999 after a long battle with cancer.
