And that's not all. The COSMO Radio Confessathon will also include confessions from people whose jobs and lives make them privy to some extra juicy scoop-like a Miami socialite who regularly parties until sunrise, a celebrity trainer who knows what the stars really do to get red-carpet ready, and two backup dancers who have performed with some of the biggest acts in pop music. The COSMO Radio Confessathon will kick off on May 5, 2007 beginning at 2:00 pm ET and will continue until 500 confessions have aired.

Geared toward Cosmopolitan magazine's audience of fun, fearless females, COSMO Radio features smart relationship advice, beauty and fashion tips, health news and entertainment information similar to what appears in the magazine, a must-read for 17 million readers each month. COSMO Radio programming also includes live talk shows, music, daily astrological predictions, and segments that give listeners a peek inside the male mind.
