Washington, Jan 10 : Madonna once secretly dated Bobby Brown, a new book claims.

In Derrick Handspike''s book `Bobby Brown: The Truth, the Whole Truth and Nothing But.', it has been claimed that no one was immune to former New Edition star's charms, not even the Material Girl, reports Contactmusic.

A publishing source told the National Enquirer, "It (romance) began when one of Bobby''s bodyguards caught the Material Girl with Bobby in the back of his limo.

"The couple met years before when Madonna was on her way up and served as the opening act for some New Edition shows.

"The book discloses, after both had become well known, Madonna was interested in having a relationship with Bobby."

It has been alleged that Brown ditched Madonna when he fell for Janet Jackson, and turned to drink when his relationship with the `Control' hitmaker soured. (ANI)
