But Carey didn't seem to want to dwell on the subject and made an attempt to change the subject.
She said: "It's kind of difficult to talk about it at the moment.
"So, I'm just going to compliment you on these decorations once again because they are fabulous, and I am here, among them."
It was recently claimed the Without You singer is "ready to move on" from James and feels relieved they never made it down the aisle.
A source said: "She's ready to move on. She feels like she dodged a bullet ... The negotiations aren't going well. At the best, she'll keep the ring."
The pair reportedly split after having an argument when they were in Greece.
A source said: "It started in Greece [with] some sort of outburst [from James] which everyone heard. [He told her,] I don't know if I can do this. I can barely take care of my own children."
And the couple failed to attend a planned meet up in Los Angeles back in October to "talk through everything as adults".
An insider claimed: "Mariah and James never met up after that. And they haven't spoken. The way the split news was handled was incredibly upsetting to her."
