Rumours have been swirling around about Lamar Odom possibly cheating on his wife Khloe Kardashian, and now his alleged gal-on-the-side is speaking out about their relationship! Jennifer Richardson in an explosive new interview, as the self-proclaimed mistress of Lamar Odom opens up about her long-term affair with the basketball star.

But she doesn't present any of that here; she simply talks in detail about how she met Odom... how serious their connection was... and how they both enjoyed a "light-hearted" threesome with her friend.

"I'm sorry," Jennifer, 29, said.

"Lamar led me to believe his marriage was just a business arrangement."

Even worse, Jennifer claims she's not the only woman that Lamar has cheated on Khloe with, and she wants her to know it.

"I can tell Khloe that I'm not the only woman; there have been many. I just happened to be around the longest," Jennifer told the magazine.

"My advice for Khloe would be to get a divorce. If she thinks he's going to change, she's mistaken."

Regardless of the explosive news of Jennifer's affair with Lamar, Khloe still wants to have a baby with him.

The cheating allegations, "of course bother Khloe tremendously. She has trust issues with Lamar and was absolutely livid when he went to a strip joint earlier this year. However, Khloe still wants to have a baby with him. She feels that once they have a baby together, it will just bring them closer," a source told Radar.

"The fertility issues have definitely taken a toll on the couple's sex life because Khloe is really strict about having sex when she is ovulating. It's become clinical, and the romance is on the back burner because Khloe is having a very hard time getting pregnant."

Khloe, in a very un-Kardashian move, has remained silent about the affair allegations.

What's cooking in? It takes two to tango and three to threesome ......
