Sean Penn married which pop star in 1985?

Sean Justin Penn (born August 17, 1960) is an American actor and filmmaker.

He met pop singer Madonna in February 1985, and they married that August on her birthday. The two starred in the panned and much-derided Shanghai Surprise (1986), directed by Jim Goddard, and Madonna dedicated her third studio album True Blue (1986) to Penn, referring to him in the liner notes as "the coolest guy in the universe". The relationship was marred by violent outbursts against the press, including one incident when Penn was arrested for assaulting a photographer on a film set; Penn was sentenced to 60 days in jail in mid-1987, of which he served 33 days.

Madonna filed for divorce in December 1987 but later withdrew the papers, only to file them again in January 1989. Madonna reportedly filed an assault complaint that she was beaten in her Malibu, California home by her estranged husband, but in January 1989, the Associated Press reported that she had "dropped assault charges". Penn was alleged to have struck Madonna on multiple occasions, but in 2015 Madonna stated the allegations were "completely outrageous, malicious, reckless, and false".
