A private concert with Mariah Carey? Yes, please.

During an interview with the Associated Press ahead of her residency at Caesars Palace in Las Vegas, the Grammy winner invited doubters to hop in the shower with her for a little sing-along.

“As far as vocals, are there going to be any kind of back-up tracks?” the reporter asked. “I know with some spectacles here in Vegas that’s just required because there’s so much going on onstage.”

Carey then defended her performances saying, “I mean, I have so many overlapping parts and background vocalists and background things that there’s always some confusion in 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.”

The singer just dropped her single “Infinity” off her greatest-hits compilation, Mariah Carey #1 to Infinity, with the album itself scheduled to be released on May 18. Her Vegas show will feature all 18 of her No. 1 hits, including “Always Be My Baby” and “Vision of Love,” and it kicks off May 6.
