Madonna is just a mom after all. The iconic singer admitted to Extra that she experienced true heartbreak after her eldest child, daughter Lourdes, left for college.

The “Like a Virgin” songstress said sending her 18-year-old, who is now a freshman at her alma mater University of Michigan, off was “really hard” and “was like the first heartbreak of my life.”

“I cried every night for weeks,” Madonna, 56, told Extra’s AJ Calloway. “I would go in her bedroom and lay on her bed and cry, it was terrible.” And with her daughter now all settled in at school, Madonna says when she visits, she's “very ‘mom.’”

"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,” she told Carson Daly in an interview on Monday, March 9. “I was worried about the fact that she didn't have enough towels, Q-tips.”

With Lourdes at school, Madge still has her other kids — Rocco, 14, and David and Mercy, 9 — to look after. “If I have dark circles under my eyes, it’s because of them,” she joked about raising her brood.
