The pop star, who rang in her birthday Friday, was spotted walking through the tony island with Ratner and a female friend. Carey, who was wearing a wrap dress and a sexy black bikini, walked arm-in-arm with the Hercules director and toted several shopping bags.
Carey split from husband Nick Cannon last August. Cannon officially filed for divorce from Carey on Dec. 12 after six years of marriage. The pair share twins Moroccan and Monroe, 3.
