It was a bit of an awkward night out for Lamar Odom.
TMZ has footage of Lamar, along with some friends, trying to enter the venue, but after several uncomfortable minutes of back and forth with promoters at the door, the basketball player leaves in defeat.
E! News reported that French was listed as a special guest that night at Penthouse and instructed the club owner not to allow the NBA free agent admittance.
An onlooker described the scene to E! News, claiming that the incident occurred as Khloe exited her vehicle along with French, sister Kim and close friend Jonathan Cheban. Supposedly, E!'s "Keeping Up With the Kardashians" cameras were also rolling and captured the whole thing.
Khloe was apparently "shocked" that Lamar, who she filed for divorce from back in December citing irreconcilable differences, was attempting to gain access into the club.
But that didn't seem to ruin the night for the partygoers, since French posted a photo on his Instagram, thanking his "BFF" Kim Kardashian for coming out to his party.
Things have been heating up between Khloe and French Montana, who's basically a Kardashian now; the pair have been repeatedly spotted out publicly together since last month.
