Washington, July 30 (ANI): Queen of pop Madonna has been accused by her estranged brother Christopher Ciccone of trying to destroy his relationship with their father, by forcing him to choose between his children.

The feud between the siblings had started after Ciccone published his explosive book - Life With My Sister Madonna - earlier this month (Jul08).

Ciccone has now alleged that Madge, after the tell-all tome was released, made their father Toby take sides, and that she even gave him an ultimatum to decide which sibling to back in the bitter row.

"The situation is now at its ugliest point, and I feel terrible for my father. Madonna's asked him to choose between me or her - but he's told her he won't do that," Contactmusic quoted Ciccone as telling Britain's Closer magazine.

"I've reassured my father that I wasn't trying to tear up the family, but I have every right to tell my side of things. I was disappointed that she thought I was going to ruin her. Of course I wasn't!

"She obviously doesn't know me as well as I thought she did," he added. (ANI)
