Lamar Odom's soon-to-be ex-wife, Khloe Kardashian, is moving on from their strained relationship with Cleveland Cavaliers player Tristan Thompson -- and he reportedly doesn't like it.

Although Lamar Odom and Khloe Kardashian haven't been involved in a confirmed romance for about three years, a new report suggests that the former athlete is unhappy with Kardashian after watching her go public with her latest relationship.

On September 14, The Stopru shared a report regarding the current relationship of Lamar Odom and Khloe Kardashian, claiming the troubled basketball player is "angry" about her romance with Thompson, which appears to be getting serious.

"She's trying to let go and have fun," added a friend.

In recent years, Kardashian hasn't had the best luck with men. Years after marrying Lamar Odom in September 2009, rumors began swirling in regard to his alleged cheating and drug use and in December 2013, the reality star filed for divorce. Following the filing, Kardashian was linked to The Game and French Montana, whom she dated on and off for about a year.

"She's cautious because of her past experiences," the source explained.

In addition to going through tons of heartache due to Lamar Odom's drug overdose in October of last year, Kardashian later revealed that Houston Rockets player James Harden, who she dated for several months at the end of last year, cheated on her during their romance.

"She seems more hopeful with Tristan — he's different than the other guys she's dated. He's a committed, relationship guy," the source said. "He showers her with flowers and rubs her feet."

Prior to his romance with Khloe Kardashian, the Toronto-born Thompson was in a long-term relationship with model Jordy C., who previously dated Tyga, the current boyfriend of Kylie Jenner and ex-fiancee of Rob Kardashian's current fiancee, Blac Chyna.

"[Khloe] doesn't know what the future holds," added the friend, "but she's having a great time!"

While Lamar Odom wasn't initially expected to survive the overdose, he got lucky and after waking up from a coma days later, he was transferred to a hospital in Los Angeles, where Kardashian continued to offer her financial and emotional support as his recovery continued. Then, after Lamar Odom was released from the hospital in January, he and Kardashian stayed close and for months, he was living in a mansion she rented for him in Calabasas, California.

For a while, things between Lamar Odom and his former partner were quite civil but now that she's cut ties with Odom and embarked on a new relationship, Odom is said to be "pissed."

"[Lamar Odom] wouldn't be so pissed about [Khloe's] dating life if she dated outside the NBA," an insider revealed to Hollywood Life. "He feels like she's hooking up with dudes in the league to f**k with him and his mental state. When he saw pics of them together he was hurt."

"[Lamar Odom] still very much loves Khloe," the insider added. "He would be back with her in a heartbeat if she'd chill out and stop trying to control every aspect of his life."
