One of the darkest chapters of Paris Hilton's life was the infamous 2003 leak of a sex tape featuring her and then-boyfriend Rick Salomon. So she was a little upset when she found out her friend Brooke Mueller was still friends with Salomon on 'The World According to Paris' (Wed., 10PM ET on Oxygen).

Hilton said she equated some of her current insecurities to that leak, at which point Mueller was a little taken aback.

"I totally thought you were involved," she said, after admitting her ongoing friendship with Salomon. Mueller was not only under the impression Hilton was involved in the leak, but thought she'd raked in half the earnings as well.

Charlie Sheen's recent behavior has been questionable on many levels. But could his actions cost him money due to a morals clause in his 'Two and a Half Men' contract? It's possible, according to the Hollywood Reporter.

Sheen entered a rehab facility for unspecified reasons earlier this week, following his arrest in on Christmas Day, in which he was accused of attacking his wife, Brooke Mueller (also in rehab for crack and alcohol addiction). He was later charged with felony menacing and misdemeanor assault.

In Hollywood, attention is now focused on the future of CBS' 'Two and a Half Men,' which Sheen recently took a leave of absence from to seek treatment. Now, the question remains: If the series has a substantial time-out because of Sheen, who's going to pay?

In terms of compelling celebrity reality shows, Denise Richards thought she had a great story to tell. Her life seemed very complicated, what with her fights with ex-husband Charlie Sheen and their legal wrangling over their children, it seemed like a compelling product.

Umm...no, it wasn't.

Today, E! pulled the plug on Denise Richards It's Complicated, her attempt to keep up with the Kardashians and outdo the Hogans. The bottom line with Denise's show was that it really wasn't that complicated. It was dull.

Her family appeared as her supporting players, including her father who -- like his children -- is still mourning the loss of his wife, Denise's mom. Those moments in the show were sad, but a little went a long way.

Denise's getting in the middle of the employment issues with her assistants was hardly great TV, nor was watching Denise driving in Beverly Hills. And, yes, the ratings were declining week after week.

Charlie Sheen has married Wife #3. The 42 year old television star married real estate investor Brooke Mueller this past Friday night. The couple have been engaged since last summer.

Sheen has starred in several movies and is currently starring in the Nielsen top-10 rated show Two and a Half Men. "She's just easy, and loving, and smart, and if everybody was just as happy to see me when I walk through a door as her, my life would be perfect," he said soon after the couple got engaged.

He is currently involved in a bitter custody battle with his ex-wife and soon-to-be-reality TV star of the E! show It's Complicated, Denise Richards. They got married in 2002 and divorced in 2006. Sheen was also briefly married to model Donna Peele in 1995.

All I can say is congratulations and best of luck to Sheen and Mueller. It's difficult to make marriages work, and even more difficult with Hollywood marriages.
