When it comes to doubts about her powerful vocal talent, Mariah Carey knows how to "Shake It Off."
The 45-year-old pop diva did just that during an interview with the Associated Press about her Las Vegas residency on Tuesday.
"As far as vocals, are there going to be any kind of backup tracks?" the female reporter wanted to know during a press conference. "There were some spectacles here in Vegas that it's just required because there's so much going on onstage."
Carey replied with a confident comeback.
"I mean, I have so many overlapping parts and background vocalists and background things. There’s always some confusion and something about it, but I mean like, if there’s any confusion they’re welcome to come to my house and sing in the shower with me."
"It’s not a problem," she insisted.
