The celebrity world really is a small once. Bravo celebrity Patti Stanger goes on the record to say that she witnessed Ramona Singer's soon-to-be ex-husband Mario cheating on her with his mistress, Kasey Dexter last year.

According to Life & Style Weekly on Friday, Stanger says she was at the same hotel the night Mario decided to start his extra marital affair with his mistress.

Stanger said, "I was there that night he cheated. I saw the whole thing go down. I was worried for Ramona. I was really worried for her ... He had, like, a midlife crisis going on and she doesn't deserve that. She's a great girl."

Just recently, Ramona, herself, slammed her ex Mario in a new interview.

According to Reality Tea last Friday, Ramona says that while her divorce has been a painful experience for her, she doesn't have any regrets.

She said, "Having your husband betray you is the worst feeling in the world. I felt emotionally bruised. I was allowing my husband to control my behavior."

Thankfully, Ramona has been able to count on the support of her friends, which includes her Real Housewives co-stars, to get through the toughest episode of her life.

She explained, "All the women on the show, including LuAnn [de Lesseps], were supportive of my situation with Mario. Without them I would never have been able to handle what I was going through. I thank all my fellow Housewives for their support and continued support."
