Mariah Carey continued her birthday celebrations with longtime pal Brett Ratner in St. Barts on Saturday. 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. Ratner, who also celebrated a birthday this weekend, and Carey have been longtime friends and collaborators, but they recently sparked romantic speculation after spending increased time together. On March 24, Ratner, 46, shared a photo dining with the “Touch My Body” singer and Courtney Love on Instagram. Earlier in the month, Carey shared a bathroom selfie of her and Ratner, who directed several of her music videos, captioning the photo “Hanging out in the girls room with @brettrat.” Despite the ongoing speculation, Ranter’s rep told PEOPLE that any reports of a romantic relationship between the pair is “ridiculous.” Carey will soon be on the move as she prepares to launch her residency at Caesars Palace in Las Vegas. The show, which launches on May 6, will feature all 18 of her #1 hits. Mariah Carey: Her Changing Looks
