Lamar Odom confronts Khloe Kardashian outside star's gym

Lamar Odom and Khloe Kardashian reportedly had an early-morning screaming match in front of the reality star's gym Wednesday morning.

According to several reports, Odom, 35, surprised Kardashian, 31, as she arrived to her Beverly Hills SoulCycle class at 6:45 a.m., demanding that the Keeping Up With the Kardashians star talk to him. When his requests were ignored, the famed NBA player allegedly touched his ex-wife's arm, prompting her to start screaming as well.

Sources tell TMZthat Kardashian was shocked that Odom found her, shouting "How did you know I was here?!" before running to her car and driving away.

The two filed for divorce in Dec. 2013 after five years of marriage. After a year and a half of waiting, the couple's divorce papers were finalized last month.

Kardashian recently told Complex magazine that she missed what she had with Odom during their relationship.

"Things we got to do together are just memories," she said. "I like looking back and holding on to that stuff. I definitely miss it, and there's times I'll get so sentimental and so sad, but this had to happen for some reason. I'll figure it out over time."

According to People, the SoulCycle confrontation may have been prompted by Odom's disapproval of Kardashian's newest flame: James Harden. The 25-year-old Houston Rockets player was reportedly spotted out with the reality star several times this month. The two even celebrated Kylie Jenner's recent birthday together.
