On Thursday, Carey shared another photo from her time on the tropical island. “Festivating in St. Barth’s!” Carey captioned the Instagram photo, which shows her dressed in a blue and coral floral dress.
“I am so so thankful for having loved ones by my side — my family, friends and fans,” Carey captioned a photo of herself and the twins with Santa Claus.
“Rebel and Mariah got on really well and they were drinking red wine and in deep conversation,” an onlooker told PEOPLE. “They seemed to have a great time.”
“They all got up and began dancing on their table when the restaurant played Mariah songs,” the onlooker added.
“#AspenCrew festive fun!
