Lamar Odom is thinking of his ex-wife, Khloe Kardashian, after her boyfriend, Tristan Thompson, was caught allegedly cheating on her.
Thompson -- who is expecting a daughter with Kardashian any day now -- made headlines on Tuesday after The Daily Mail obtained video of what appears to be the 27-year-old Cleveland Cavaliers player kissing a mystery woman in New York City. However, a source exclusively tells ET that he and the woman were talking, "nothing more."
Another source tells ET that upon learning of the cheating scandal, Odom has expressed sympathy for Kardashian. "Lamar has been telling close friends that he genuinely feels bad for Khloe," says the source.
ET has reached out to Odom's rep regarding the recent allegations against Thompson.
While he may have compassion for Kardashian, the 38-year-old former NBA pro has admitted to being unfaithful to the 33-year-old reality star while they were married.
"When I became Khloe Kardashian’s man and on TV, it made me look more enticing," he told Us Weekly in a May 2017 interview, referring to when the two starred on their own reality show. "People who didn’t even know basketball would approach me because they knew Lammy."
"If there is one thing I regret when I was married, it was having multiple affairs with different women," he continued. "That wasn’t the stand-up thing to do."
Kardashian has also spoken out about Odom's cheating, and claimed in a January 2016 interview on Howard Stern's Sirius XM radio show that he had been cheating on her for "the majority" of their marriage.
"I'm genuinely blown away as to when he fit that in," she said. "Lamar was so great at making me feel like I was the only one and I'm this princess. I never speculated cheating."
Kardashian said she did inquire as to why Odom cheated on her. "I've always asked why and obviously Lamar did struggle with substance abuse," she continued. "I do believe there's a sex addiction, but I also don't know if I believe in a sex addiction that much."
When asked if she regrets marrying Odom after only a month of knowing him, Kardashian confessed, "I don't think I would do it again, but I don't regret what I did."
Cut to present day, a source close to the Kardashian-Jenner clan tells ET that the family is in crisis mode upon hearing of Thompson's alleged infidelity
“Friends are shocked and didn’t see this coming," the source says. "They seemed to be in a really good place."
