Even superstar moms can be embarrassing to their kids sometimes! The University of Michigan used to be Madonna's playground, but it's now home to her daughter Lourdes, 18 — and while the football team would probably love to have the Material Girl cheering them on from the stands, her oldest child apparently wouldn't.

"I'm not allowed at games," the "Living for Love" singer, 56, told the Today show's Carson Daly. "You think my daughter wants me at a game?"

When she does visit the campus, she added, it's as a mother, not a celebrity.

"I'm very 'mom,'" she said of how she acts when she's there. "I'm very, you know, worried: 'Are you okay? Are you getting enough sleep? Are you eating right?' You know, I set up a humidifier in her room with eucalyptus oil. I was worried about the fact that she didn't have enough towels, Q-tips." 

The star — who also has three younger kids, Rocco, 13, Mercy, 9, and David Banda, 9 — attended the University of Michigan in the late 1970s, but dropped out to pursue a professional music career in New York City. She has some ideas about how her daughter can make the most of her time there, though. 

Asked what advice she gave to Lourdes before her first day, Madonna told Daly, "Try to do everything in moderation. Try not to kill all your brain cells. And try to go to class."
