Age Before Beauty, I Suppose

Hiss!:

MADONNA reportedly laughed "hysterically" after being told her pop rival Mariah Carey had to cancel several tour dates due to poor ticket sales.

The Hung Up singer is said to have gleefully welcomed the news that Mariah had to shelve a host of US shows because of a lack of interest.

A source told America's New York Daily News newspaper: "Madonna laughed hysterically. She has been asking her tour promoters to email her Mariah's sales."

It is believed Madonna still holds a grudge against the Butterfly singer because of something she said in an interview years ago.

The 47-year-old star is believed to be irked that Mariah, 36, once said she "grew up" listening to her music.
