Things between Khloe Kardashian and her ex-husband Lamar Odom might be getting a little flirty.

In a report by Latin Post, Khloe Kardashian and Lamar Odom might have called it quits two years ago but it doesn't mean that they are over each other. In the recent episodes of "Keeping Up With The Kardashians," Khloe seemed more than happy to be talking to her ex-husband Lamar Odom.

In the preview for the next episode, it showed Khloe hanging out with Kim in the kitchen when suddenly she got a call from ex-husband Lamar. It was obvious that she could not contain the happiness as she talked with her ex over the phone.

Now, although Kim has been casual about her sister's friendship with Lamar, she doesn't seem very happy about the recent developments with Khloe and Odom's relationship.

"As a big sister, I'm protective. For her to just be flirting with him on the phone makes me sick to my stomach," Kim said.

In another article by Mirror UK, Khloe proves that she still has Lamar's back, most especially through difficult times. Lamar's friend Jamie Sangouthai died and Khloe expressed her concern about how it would affect her ex-husband.

"Lamar's best friend since he's been like 12, Jamie, just passed away unexpectedly. This is all just really upsetting. He's distraught and devastated," Khloe confessed. "Lamar has suffered so much loss in his life. I'm always going to be there for Lamar, especially when something as tragic as this happens."

Khloe added that she is "high alert" when it comes to Lamar because she understands that anything could set him to spiral, and that is one thing she doesn't want to happen.

Khloe and Lamar announced their split in 2013 after being married for four years. It was believed that the couple had been separated for a few months before Khloe filed for divorce in December of 2013. There were rumors that Odom was struggling that time with substance abuse. There were also claims that Lamar cheated on Khloe.

Rekindling their romance seems impossible right now because Khloe is currently dating NBA star James Harden. They recently gave the public some display of affection when they were spotted at a UFC fight event. The two have reportedly been dating since July when the couple were first seen in public in Las Vegas.

"They walked in holding hands. They were laughing and whispering into each other's ears," a source said.
