Madonna may be even more surprised that brother Christopher is writing a tell-all, since the two have stayed in touch during their father's bout with prostate cancer, one family friend tells us. He concurs with Rupert Everett's contention that Madonna's husband, director Guy Ritchie, is "uncomfortable around queens," saying, "Guy is a homophobe. At their wedding, Chris made a joke about Guy being gay. That set the tone for their relationship. Chris calls Guy's accent 'Mockney.' He's a well-born person who pretends to be from the street. If he and Madonna ever split up, you'd see her go right back to Chris."
