Two and a Half Men star Charlie Sheen is suddenly minus a woman.
Denise Richards filed for divorce from Sheen Wednesday after nearly three years of marriage.
According to the divorce petition filed in Los Angeles Superior Court, Richards cites irreconcilable differences for the split.
The couple have a daughter, Sam, who turns one next week, and Richards is six months pregnant with the couple's second child, who is due in early June. The actress wants custody of the children and is seeking spousal support payments from Sheen.
"We are deeply saddened by the recent events and out of care and concern for our daughter Sam, our unborn child, and each other, we ask that you respect our privacy during this difficult time," the ex-couple said in a joint statement.
In happier times, Sheen, 39, and Richards, 34, were inseparable, costarring in projects and gushing about their mutual admiration.
The couple first shared credits in 1993's Loaded Weapon 1, the Lethal Weapon parody starring Sheen's older bro Emilio Estevez. They reteamed for the little-seen 2001 romantic comedy Good Advice and later clicked when Richards guested in Sheen's Spin City.
By their second date, Richards was hooked. "I knew that this is the one, but I wouldn't tell him that," she told People. "I didn't want to scare him away by saying, 'You're my future husband!' and have him run for the hills."
Richards convinced Sheen to put an end to his bad-boy bachelor ways in June 2002, when they tied the knot in a small ceremony attended by all-star family members, including dad Martin Sheen.
It was the first matrimonial go-round for Richards and the second time down the aisle for the youngest member of the Sheen clan, who was previously hitched to model Donna Peele. That marriage lasted a whole year before ending in divorce in 1996.
Sheen also was engaged but never married to Kelly Preston (whom he accidentally shot in the arm--just one of the mishaps that occurred during Sheen's hard-partying past), and he also has a 20-year-old daughter, Cassandra, with high school girlfriend Paula Profitt.
The couple also split screen time in 2003's Scary Movie 3 and Richards twice appeared on his current CBS sitcom, Two and a Half Men, most recently during a sweeps episode last November.
Aside from his TV gig, Sheen (né Carlos Irwin Estevez) is reportedly mulling a sequel to Money Talks with Chris Tucker.
Richards, best known for stints in Wild Things and as a Bond babe in The World Is Not Enough, was last seen in a Fat Albert cameo. She also has a small role in David Mamet's Edmond, which is currently in production and slated for a December release.
