Madonna is pure confidence on stage, but off she sometimes struggles with the insecurities that come with parenthood.

"Seeing my daughter at 16—it's kind of uncomfortable," the 54-year-old star says of Lourdes. "She's still my little girl and she's also a woman."

As for her 12-year-old son, Rocco, he's "a foot taller" and is "looking at girl's butts," says Madonna, who jokes she finds the situation "terrible."

Madonna revealed her parenting woes during an interview with Good Morning America to promote her new documentary, Madonna: The MDNA Tour, which she shot while touring around the world in 2012.

The singer, who calls herself "pretty strict," notes that she is doing her best to raise her kids to appreciate what they have. She says that the documentary shows how Lourdes had the "very unglamorous task dressing and undressing the male dancers," as part of her job with the wardrobe department. "They're disgusting and they're sweaty and they're rude."
