Harry Hamlin recently got in on the action of The Real Housewives of Beverly Hills.

Did Kim Richards Accuse Lisa Rinna Of Having An Eating Disorder On 'RHOBH?'

Since last week's episode aired, Hamlin has been joking that he is guilty of whatever it is Kim Richards claims he did, and his latest tweet, Hamlin continues to poke fun at the secret reality scandal.

"Apparently it's all my fault," Hamlin tweeted on Friday. "Mea Culpa!! Mea Culpa!!"

Harry Hamlin Speaks Out About Kim Richards' Attack On Lisa Rinna

On Tuesday night's new episode of The Real Housewives of Beverly Hills, the ladies were seen in Amsterdam, where they took in the sights, and enjoyed a couple of dramatic dinners. During one dinner, in particular, things became heated between Richards and Lisa Rinna, Hamlin's wife, and Richards alleged Rinna was dealing with a "situation at home." She didn't, however, reveal what that situation was.

On Twitter, Rinna has faced drama as well. On Friday, a woman tweeted to her and Lisa Vanderpump, claiming Rinna had no room to judge anyone since she's appeared in Playboy.

After seeing the tweets, Rinna had no problem admitting to her racy past.

"Newsflash. I did Playboy. Twice," she wrote.

In 1998, while sixth months pregnant, Rinna posed for Playboy, appearing on the cover of their September issue. Then, in May 2009, Rinna was seen on the cover yet again.

Vanderpump also spoke of the issue, asking, "What has playboy got to do with anything?"

The Real Housewives of Beverly Hills airs Tuesdays at 9 p.m. on Bravo.
