LONDON? - Madonna's pay-packet, Janet Jackson's malfunctioning wardrobe, Hillary Clinton's memoirs and Sigourney Weaver's height all have one thing in common -- they're world record breakers.

Veteran pop singer Madonna supplants younger rival Britney Spears in the latest edition of Guinness World Records, winning the title of highest annual earnings by a female singer after she took home an estimated $50 million in 2004.

Despite the relentless media coverage of her personal life, Spears is also unseated by another 40-something as the world's most searched-for person and most searched-for news item on the Internet.

She loses those top spots to pop diva Janet Jackson who also gets credit for the largest ever fine imposed on a broadcaster after one of her breasts was exposed live on air.
