Mo'Nique on Sex Outside Marriage: 'That's Not a Deal-Breaker'

March 4, 2010 — -- For Oscar nominee Mo'Nique, sex outside of marriage is "not a deal-breaker."

In the 29th and final "Barbara Walters Oscars Special," Mo'Nique opened up to Walters about her almost-four-year marriage to childhood friend Sidney Hicks.

Mo'Nique said it is an open marriage, which she defined for Walters as "no secrets."

"Open means, you know what, let me tell you my every secret, my fantasies, my thoughts, so that way, there are no surprises," Mo'Nique said.

When asked by Walters if the couple had sex outside of the marriage, Mo'Nique said: "Let me say this: I have not had sex outside of my marriage with Sidney. Could I have sex outside of my marriage with Sidney? Yes. Could Sid have sex outside of his marriage with me? Yes. That's not a deal-breaker."

Walters pressed: What if it happened more than once?

Mo'Nique: 'I'm Very Comfortable and Secure With My Husband'

"What if it's 20 times?" said Mo'Nique, who has twin boys with Hicks and a son from an earlier marriage. "That's not something that ... would make us say, 'Pack your things and let's end the marriage,' because we've been best friends for ... is it over 25 years? And we truly know who we are. Truly.

Oftentimes," she added, "people get into marriages and they don't know who they're laying next to. I'm very comfortable and secure with my husband."

Mo'Nique, 42, is poised to take home a best supporting actress Oscar for her portrayal of an abusive mother in "Precious: Based on the Novel 'Push' by Sapphire." The star already has won a Screen Actors Guild Award, a Golden Globe Award and the British Academy of Film and Television Arts (BAFTA) Award for her performance.
