3AM: Mariah Hits the thigh notes.

Byline: Eva Simpson & Caroline Hedley

NOW here's a woman with total confidence in her fabulous body.

Pop beauty Mariah Carey (right) kicked off her Adventures Of Mimi tour at the American Airlines Arena in Miami on Saturday with the most adventurous of costumes for her lucky fans.

A friend of the superstar singer, 36, who changes outfits an incredible nine times during the show, tells us: "Mariah is more toned than she's ever been before - and she wants to show off the fruits of her labour."

And no one in the audience could say that all those hours in the gym weren't well spent.
