Polina Polonsky, the second woman to come forward claiming a relationship with Khloe Kardashian's husband, Lamar Odom, says she met the NBA player the same night Kim Kardashian held her baby shower!

Polina, 33, claims she's known Lamar for quite some time, but that the romantic relationship between the two didn't begin until the night of June 2, after he'd left his sister-in-law's baby shower — which coincidentally enough, was the last time Khloe and Lamar were photographed together.
