Mariah Carey is flying high from her 18th #1 hit "Touch My Body," and she's been all over the place promoting her new album (Oprah yesterday, American Idol tonight), E=MC² which came out today. But remember when things were going so great in her career about seven years ago, specifically when she freaked out in the summer of 2001 from not sleeping? (Remember when Glitter was the first time we could all truly laugh after September 11?) Above is a clip from her July 2001 surprise appearance on TRL, in which she wore a skimpy outfit, handed out popsicles, and rambled about stuff that didn't make any sense. ("All I know is I just want one day off when I can go swimming and look at rainbows and like eat ice cream. And maybe like learn how to ride a bicycle.") A few days later, she checked into a mental facility. We're glad she's feeling a lot better and is back on top, but we kinda thought she was equally entertaining while hitting rock bottom.
