It's not difficult to guess why as Charlie and Denise's once amicable relationship has grown increasingly strained in the past few months with him lashing out at her on Twitter and things have gotten so bad that Denise is reportedly set to move out of the mansion he owns in the Mulholland Estates neighbourhood in Beverly Hills.
The Anger Management actor's porn star girlfriend Brett Rossi, who lives in the same gated community with Charlie, persuaded him to oust Denise from the $7 million home he also owns, the site reported.
In May 2010, Richards was handed over custody of her and Sheen's two daughters by Sheen.
The two signed a written agreement stating that she now has sole legal custody of Sam and Lola.
Later that year, Richards starred alongside Kirsten Dunst in the beauty pageant satire, Drop Dead Gorgeous.
