What is that saying about a leopard never changing it spots?

Just two weeks ago we learned about an official breakup between Karina Smirnoff and Mario Lopez. Now we’re getting word about a possible factor in their relationship’s demise. According to a former Hooters calendar model, Lopez had been cheating on his Dancing with the Stars partner for nearly a whole year.

In an interview with E!, Meagan Cooper said that she was led to believe Mario had broken up with his ex. She continued to buy that story despite the fact Karina had left belongings in his home…and despite the fact that he had cheated on his first wife. (Lopez and Doritos Girl Ali Landry were married for less than two weeks back in 2004; she reportedly found out about his alleged infidelities shortly after their nuptials.)

Now realizing the Chorus Line star had been lying to her the whole time, a very bitter Cooper has chosen to expose Mario’s slimy ways.

“We’re not friends anymore. He’s really pissed. He’s like, ‘You’re not supposed to talk to [press],’ but when you make me look like a total whore, I’m going to tell somebody about it.”

Surprisingly, Meagan did manage to throw in a few kind words about her ex (which only, in my mind, lends to her credibility). “He’s a really great guy, don’t get me wrong. He’s a really nice person. He has a lot of great qualities, but he was not the most faithful person in the world.”

Well - there you go, ladies. Don’t say you weren’t warned.
