Mariah Carey and Nick Cannon remain the friendliest of exes following the singer's split from her ex-fiance, billionaire businessman James Packer.

The two recently reunited to spend Thanksgiving as a family with their twins, 5-year-old Monroe and Moroccan, and a source close to Carey tells ET that the former couple are currently in "a great place." Carey and Cannon celebrated in Hawaii, where the "All I Want for Christmas Is You" singer performed a concert on Friday.

"Nick has been really supportive and amazing," the source says. "They are in a great place and had a wonderful festive Thanksgiving with the kids in Honolulu and they all helped cook together."

Meanwhile, the source says financial negotiations between Packer and Carey are still "going nowhere. "But when it comes to her 35-carat, $10 million engagement ring and whether Carey gets to keep it, the source says Packer's camp is "leaving that alone for now."

Carey and Cannon split in 2014, and have both moved on. Cannon is now expecting another child with his ex-girlfriend, Brittany Bell. Though 36-year-old Cannon and Carey are obviously still on friendly terms given their choice to spend Thanksgiving together, last week, a source close to Carey told ET that Cannon's big baby news is "still a sensitive topic" for the 46-year-old GRAMMY winner.

It's certainly been quite the year for Carey, who got engaged to Packer in January, before the two split in October. ET recently spoke to the legendary singer, when she talked about what it's like re-watching footage of herself trying on what was supposed to be her stunning wedding dress to Packer for her upcoming reality show, Mariah's World.

"All of those moments are bittersweet," Carey said, "but you just have to focus on whatever you're focusing on and keep it moving."
