The backup dancer — who has been a fixture on his girlfriend’s tours since 2006 — was not onstage when Carey kicked off her “Merry Christmas One and All!” shows on Wednesday night at Yaamava’ Resort & Casino in Highland, Calif.

Additionally, social media users pointed out that the Grammy winner, 54, seemed unusually downcast during the opening night of her typically upbeat holiday concerts.

“Every clip I’ve seen she looks like she doesn’t want to be there,” one fan tweeted.

“She looks depressed, like something is going on behind the scenes,” another agreed.

“Girl going through break up era !!!” a third Twitter user surmised.

Others wondered why Tanaka, 40, was absent from the performance.

“I don’t see Bryan Tanaka. Where is he?” one fan asked.

“Streets saying Bryan wasn’t at Mariah concert last night and she was looking sad are they really done,” another tweeted.
