It's been a known thing for a while but is always really swept under the rug because he apparently ~cleaned up his act. I didn't learn about it myself until last year.

Here you go:

"In June 1987, Madonna went to the Cedars Sinai hospital for an X-ray after Penn apparently hit her across the head with a baseball bat. At the time, they had been having a heart-to-heart talk about reconciling.

Madonna did not make an official complaint because Penn was about to serve a short jail term for attacking a film extra. He served 33 days of a 60-day sentence in the Los Angeles County jail (23 hours a day in solitary) for violating the probation he'd been given for punching a fan.

It was a decision she would come to regret. In the late afternoon of December 28, 1988, Penn scaled the wall surrounding the Malibu house and found Madonna alone in the master bedroom.

According to a report filed by Madonna with the Malibu sheriff’s office, the two began to quarrel. Penn told her he owned her ‘lock, stock and barrel’. When she told him she was leaving the house, he tried to bind her hands with an electric lamp and cord. Screaming and afraid, Madonna fled from the bedroom. What followed was a nine-hour ordeal which left her deeply shaken.

Penn chased her into the living room, caught her and bound her to a chair with heavy twine. Then he threatened to cut off her hair.
According to the police report, Penn was ‘drinking liquor straight from the bottle’ and the abuse went on for several hours, during which time he smacked and roughed up his victim.

He went out to buy more alcohol, leaving Madonna bound and gagged. Some hours later, he returned and continued his attacks.
Madonna said that he untied her after she agreed to perform a degrading sex act on him. She then fled the house and ran to her car.

Penn ran after her and was banging on the windows of her Thunderbird while she spoke to police on her mobile phone. Fifteen minutes later, she staggered into the sheriff’s office.

Lieut Bill McSweeny said: ‘I hardly recognised her as Madonna. She was weeping, her lip was bleeding and she had obviously been struck."


*Nine hours, not almost a day, got it wrong.
