Madonna's Brother Denies A-Rod Affair

Madonna's brother Christopher Ciccone has no problem trashing his sister in his new book, Life With My Sister Madonna, but he says an affair with Alex Rodriguez is "highly unlikely."

Ciccone appeared on Good Morning America this morning to talk about his upcoming book and her alleged affair.

"I think that he (Rodriguez) was interested in Kabbalah to be honest... We (Rodriguez and I) have met a number of times. I doubt this is an affair.. I'm sure she had nothing to do with the break-up of their (Rodriguez') marriage. It seemed absurd to me truly. I don't believe it."
