Weeks after they appeared at the 2005 Golden Globes, news broke that six-months-pregnant Denise Richards had dumped hubby Charlie Sheen. Was it her hormones? His past? Neither said, but Richards filed for divorce. Although they briefly reconciled, they split for good in early 2006. Richards is single after a run with Richie Sambora, and Sheen was married to Brooke Mueller, with whom he had twins, but the couple split after Sheen was found guilty of assualting her during Christmas 2009.
