Jennifer Richardson pictured: Lamar Odom’s alleged mistress posing for InTouch magazine

Jennifer Richardson, one of Lamar Odom’s alleged mistresses, has opened up to InTouch magazine about her purported year-long affair with the NBA star, claiming the Kardashians had her followed “for weeks”.

Jennifer Richardson, 29, who said she met Lamar Odom, 33, at a club in January 2012, said she believed Khloe Kardashian, 28, found out about their affair and had her followed.

“They had private investigators following me for weeks,” claims the LA entrepreneur.

“I was very, very intimidated and scared.”

Jennifer Richardson said she believed Khloe Kardashian had Lamar Odom trailed too.

“She’s constantly looking for Lamar and trying to find out where he is, calling him, calling his assistant,” she said.

“Lamar would just hit <<ignore>>.”

Before their affair ended last March, Lamar Odom told Jennifer Richardson he wanted to get her pregnant, despite his wife’s struggles to conceive, she said.

“We talked about how much he wanted me to have his baby,” said Jennifer Richardson.

“Lamar is baby crazy – that’s all he talks about. That was probably 70 percent of our conversations.”

Jennifer Richardson did not use birth control, and although she didn’t become pregnant, there were some scares.

“I’m not going to lie, I thought I could be [pregnant] a few times,” she said.

Jennifer Richardson opened up about their love life, claiming that Lamar Odom was “very good” in bed.

“He’s an emotional, affectionate, freaky lover,” she said.

“The chemistry was deep and intense.”

Jennifer Richardson also penned a handwritten to Khloe Kardashian, claiming she didn’t mean to hurt the reality star but that she was “in love with Lamar”.

“My intentions are not and have never been maliscious [sic] or to harm what you and Lamar share,” and “your fans and so many young women admire and look to you for strength. They deserve to know your marriage is not perfect.”

“Khloe puts on a brave face for the public,” she said.

“It’s like she just wants to be that perfect, white picket-fence family – everything she knows it will never be.”

Meanwhile, rumours that Khloe Kardashian and Lamar Odom are filing divorce papers on Wednesday are “not true”, Khloe’s mother Kris Jenner told TMZ on Wednesday.

“Khloe and Lamar are absolutely not getting divorced. There’s been no talk of divorce.”

Kris Jenner added Khloe Kardashian and Lamar Odom  were at her house two days ago and “everything was fine”.

Since Jennifer Richardson came forward with the allegations, another woman has claimed she too had an affair with the basketball player.

Lawyer Polina Polonsky, who said she had a six-week fling with Lamar Odom, told Star magazine she hooked up with him the night of Kim Kardashian’s baby shower on June 2.

“I was under the impression that he had left Khloe, and that’s why he was living at the Roosevelt,” she told Star Magazine.

The magazine claimed Khloe Kardashian was “devastated” about Polina Polonsky and tracked down the cheating pair at various hotel rooms.
