The couple, who had a 14 year age gap, had Tanaka, 40, wanting to start his own family with Carey, 54.
“He wants to have a family. That’s not where she is at,” says a source who spoke to Page Six.
Carey currently shares 12-year-old twins Moroccan and Monroe with ex-husband Nick Cannon. Tanaka does not have any children of his own.
The “Fantasy” singer and backup dancer were together for seven years before calling it off.
Many had questions this week when the Queen of Christmas went on her annual trip to Aspen, Colorado solo.
Tanaka was also missing from the “Merry Christmas One and All” tour that started back in November at the Yaamava Resort & Casino in Highland, California.
Tanaka worked as a dancer with Carey starting back in 2006 and the two started dating in 2016.
“He wants to start having his own life,” another source told us of the split.
Carey previously told People earlier this month that she had a tough year, which also raised suspicions.
“I’ve been looking forward to this Christmas for, like, the whole year. Since last year — because last year wasn’t the greatest,” the “Obsessed” songstress said.
“I’m thankful for them all, but it wasn’t my most fun version of Christmas ever.”
Carey also vowed to “have fun” during the 2023 holiday season “come hell or high water.”
The songstress spent her birthday in March with Tanaka and were spotted together.
Carey broke it off with Tanaka in 2017 but the two ended up getting back together shortly afterward.
