June 19, 2008 -- Just when it seemed Denise Richards and Charlie Sheen had finally tired of throwing punches, she pulled an uppercut — a.k.a., a three-year-old, expletive-laced voice message from Sheen.
Sheen, star of "Two and a Half Men," followed up by releasing an apology for what he called his "choice of words."
The voicemail Richards made public Wednesday included a curse-filled rant from Sheen calling his ex-wife — and the mother of their two daughters Sam, 4, and Lola, 3 — a "f***ing c**t" and a "f***ing n****r."
Sheen shouldn't have been surprised by his ex-wife's bomb-drop. In an interview to promote her new E! reality TV show (which features their children), Richards told the upcoming issue of TV Guide that she's not taking the high road with her ex-husband anymore.
"The gloves are off," she said. "When I keep my mouth shut, [Charlie] continues to fuel [the feud] anyway, so I'm not gonna sit back anymore."
Richards, 37, and Sheen, 42, have been fighting over the custody of their daughters since April 2006. What provoked Richards' latest attack? It could be that Sheen allegedly tried to take back some necklaces he gave to his daughters when they attended his May 30 wedding to Brooke Mueller.
"When they came home I was told by the nanny they had to give them back," Richards told TV Guide. "I said, 'But aren't they a gift?' The nanny said, 'They are, but they can only wear them at his house.' I said, 'Have him call his lawyer then, 'cause I'm not gonna tell a 3- and 4-year-old, 'You have to give back the necklaces Daddy gave you and only wear them at Daddy's house.'"
"Now, I know this sounds f***ing crazy — and it is. But this is what I deal with," she ranted.
Sheen's publicist, Stan Rosenfield, told ABCNEWS.com Richards' necklace allegation "is not true" but declined to elaborate further. He did release a statement from Sheen in which he appeared to apologize to everyone but Richards for his outburst.
"I deeply apologize by my choice of words to all I have obviously offended; especially to Tony Todd, an African-American, who was my best man at my first two weddings," Sheen writes. "And for the record, my children did not show up today for a custodial visit without explanation. So three and one-half years later, the reasons that caused the anger and frustration displayed on that voice mail continues to be manifested on a daily basis."
Richards' publicist did not respond to ABCNEWS.com's requests for comment.
