Once upon a time, Khloe Kardashian and Lamar Odom were a happy couple. However, things changed in their marriage and ended up with Khloe filing divorce from the basketball athlete. Khloe may have gone her own way and moved on without Lamar in her life, then the ex-lovers accidentally saw each other. Now a source claims that Khloe thinks Lamar is pestering her.

It all started with Lamar showed up at a nightclub in West Hollywood where Khloe's rumoured boyfriend French Montana was performing. The basketball athlete wasn't able to get inside because the club's management decided not to let him in for fear of starting a scuffle. Khloe and Lamar have been living separately for so long. She filed for divorce in December.

A source told Hollywoodlife.com that Khloe was stunned after seeing Lamar and wasn't really pleased about it. Khloe thinks she's being "stalked," according to the source.

"She was shaking her head in disbelief as she was walking up the long staircase to get inside the club," revealed the source. Khloe didn't have the slightest idea the she would see Lamar there.

"She couldn't believe he was there."

According to the source, Lamar's presence at the club was more like a stalking scenario. The source further alleged that Lamar knew French was there because of all the promotions that the rapper and club did. True enough. French even promoted his gig at the club on social media.

"What a stalker."

"French Montana is well-known here and he and the club publicized he would be there, I'm certain Lamar knew that," the source added.

Restraining Order Against Lamar

Khloe reportedly doesn't have any problems filing for a restraining order against Lamar if she needs to, as reported by the same entertainment news Web site. Though the source claims that Khloe still has feelings for Lamar, she sure wouldn't mind "having a restraining order against him." It isn't something personal, but Khloe doesn't welcome the idea of Lamar showing up just like he did.

"She doesn't want to hurt his feelings or send over the ledge but he cannot do things like that."
