AceShowbiz - Denise Richards once had an unlikely guest at her Thanksgiving dinner due to ex-husband Charlie Sheen. In the latest episode of "The Real Housewives of Beverly Hills", the blonde actress recalled the time when her actor ex-husband brought a prostitute on the special occasion, joking that the "Two and a Half Men" alum "aged me terribly."

The conversation came up when she was enjoying lunch with ex-boyfriend Patrick Muldoon at a location of a Christmas movie they were filming together. "Charlie came over for Thanksgiving for dinner a few years ago, and he had a hooker in the car in the driveway," she later explained in a confessional. "He was afraid to tell me, 'Uh, you know, well, she's in the driveway. Is it okay if she's in the driveway?' "

The "Wild Things" star continued, "I said, 'Ugh. I'll set a f***ing plate.' Even a hooker deserves to have Thanksgiving dinner!"

Denise and Charlie split in November 2006 after four years of marriage. Despite their public and dramatic split, the former couple has now remained close friends and continued co-parenting their two children, Sam (15) and Lola (13). In a previous episode of "RHOBH", Denise opened up about the difficulties that the two need to face while co-parenting together.

Admitting that things became hard once their daughters reached teenagehood, she said, "I think a lot of parents who are divorced are probably going through this. Especially when they become teenagers. It's really difficult. If they are gonna experiment with drugs, it's usually then. Or alcohol. Or have sex for the first time."

Denise also recalled the time when she banned her daughters from using cell phones, only to find out that Charlie had given them new ones. "I took the phone away from my kid and her dad was in total agreement on the phone with me and he supported it. The next day, a new phone number," she said, adding that "it was hard."
