Madonna has reportedly banned her support acts from speaking to her. The "4 Minutes" singer - who is currently on her "Sticky and Sweet" world tour - is said to be refusing to socialize with artists who open her show.

Madonna has been forbidden from cutting her hair by husband Guy Ritchie. The 50-year-old singer - who has been sporting long blonde locks on her current "Sticky and Sweet" tour - is desperate for a radical new style, but Guy is less than thrilled with the idea.

Madonna and Alex Rodriguez were spotted enjoying dinner together earlier this week. The singer and the baseball player - who were rumored to be having an affair earlier this year - sat in "an alcove-like table" at the back of New York eatery Dos Caminos Third Avenue on Tuesday.
