Madonna's brother is set to further embarrass the pop star - he's reportedly planning a reality TV show based on his life as her sibling.

It was announced earlier this month that Christopher Ciccone is writing a tell-all memoir about the superstar, to be published without her permission, with infamous celebrity biographer Wendy Leigh.

And now Ciccone, 47, is allegedly shopping around a show that will focus on the fact he's her brother.

A source tells New York gossip column Page Six, "He hasn't gotten a deal yet, but he's been pitching it around."

Madonna's relationship with her younger brother is said to have become strained in recent years, even though the pair worked together intimately in the early 1990s, with Ciccone serving as artistic director on the star's 1991 documentary In Bed With Madonna, and designing and directing her Girlie Show tour in 1993.
