Mimi sure let it all hang out!

Mariah Carey took the stage in Chengdu in the Sichuan Province of China on Friday, and concertgoers got quite the show when she flashed her crotch in a microscopic skirt while belting out the hits. The Grammy winner's outfits are either getting smaller, or she's getting bigger, because not only was her underwear showing, but her cleavage was spilling out of her corset top. Yikes!

The poor pop diva has had a bit of a hard time lately. The mother-of-two split from husband Nick Cannon in August, and she was recently panned for a performance in Tokyo, where she struggled to sing and forgot the lyrics to her tunes. Let's hope she's not headed for another breakdown, but it appears it might be unavoidable with all this stress.

"She's showing a lot of the same symptoms she did before her 2001 emotional meltdown [during which she was hospitalized for a month and received psychiatric care]. She's drinking too much, talking to herself and refers to herself in the third person. Mariah is going to get a lot worse before she gets better," a source recently revealed to In Touch.

Somewhere, Nicki Minaj is laughing hysterically!
