Lamar Odom's alleged mistress makes first public appearance since rumours

The woman, who allegedly had a yearlong affair with Lamar Odom, stepped out on Friday night for the first time since rumors began flying about their purported dalliance.

A source had told Star that Odom had been cavorting with Richardson, 29, behind wife Kardashian's back since January 2012.

Apparently, Richardson met Odom at the Stadium Club in Washington and traveled to North Carolina and Los Angeles to meet him. Richardson supposedly has evidence of the affair, including plane tickets and basketball ticket receipts, the New York Daily News reported.

It is reported that Kardashian kicked Odom out of their shared mansion in January over the infidelity.

The 33-year-old star even went ballistic at a crowd of paparazzi that questioned him about the alleged affair. He snapped back saying that he would never cheat on his wife and that's why he wears his wedding ring.

He trashed several photographers' cameras and cars at a light near his Los Angeles home.
