Madonna is defending her decision to include 9-year-old daughter Lourdes and 4-year-old son Rocco in her new documentary, "I'm Going to Tell You a Secret," which debuts Friday on MTV. The suddenly ubiquitous pop icon tells MTV that while she doesn't want to exploit her dairy- and pop culture-deprived offspring, the film "would be a lie" if they weren't in it. "It's a fine line to walk," says Madonna, who explains that the footage with Lourdes and Rocco was filmed by a family friend, so "everyone was very comfortable. Honestly, they didn't even know [the cameraman] was there. They just sort of behaved as they normally do."

One person who probably won't be TiVo-ing Madonna's latest intimate portrait is Jon Bon Jovi, who takes issue with stars who expose their children to the public eye. "She can say what she likes but Madonna takes those kids out to every premiere she ever goes to," the follically challenged rocker and father of four rails to the London Mirror. "These kids have done nothing and yet we all know what they look like? It's crazy, man, but each to their own." (In Madonna's defense, neither Lourdes nor Rocco has accompanied her on her recent promotional pit stops). Brags Bon Jovi, "My kids don't have security guards outside their school because no one knows what they look like. And that's the way I'm going to keep it."






Follically challenged?? Ouch!!!
