Madonna's brother Christopher Ciccone claims her ex-husband Sean Penn was "the love of her life."

The 'Material Girl' singer - who was married to "Mystic River" actor Sean from 1985 to 1989 - says she has never truly got over her split from Sean.

He said: "Sean was definitely the love of her life."

Christopher - who recently blamed Madonna's current husband Guy Ritchie for his estranged relationship with his sister - also revealed he and Sean bonded in a unique way.

He added to US TV show "Extra": "He cut my thumb open - he cut his open - we pressed them together and he was like, 'OK, cool - now we're blood brothers!' "

Later in the explosive interview, the artistic director claims he once found Madonna's ex-boyfriend Warren Beatty going through her rubbish, shortly before their relationship ended.

He said: "I see a shadow going through the garbage can, I look over, and I realize it's Warren. I think they were both suspect of each other, as far as being true."
