There's a "he said/she said" battle brewing between Melissa Rivers and Jay Leno.

Rivers claims Leno - who famously feuded with Rivers' mother Joan by following in the footsteps of his predecessor Johnny Carson and refusing to allow her on The Tonight Show- snubbed her at an event a few months after Joan's death.

In December, Rivers was asked to speak at The Hollywood Reporter's Women in Entertainment breakfast, which was her first public appearance since her mother's death in September. "I walk in, and I'm standing, having a coffee in the reception area, and Jay ... looks right at me, and looks away," Rivers told Howard Stern on his radio show Wednesday morning. "I sort of wrestled with this. Don't you think you still walk over and say, 'I'm so sorry about your loss, how are you doing?' Or, 'I know there was an issue, but please accept my condolences. ... It would have been closure, and it would have been the right thing to do."

However, Leno's camp tells a different story, saying Leno wasn't aware of Rivers' presence. "If he made eye contact with her, he didn't recognize it was Melissa," Leno's rep told Us Weekly in a statement. "Had he done so, he would've come over to extend his condolences. He apologizes if she was offended, but he did not realize it was Melissa."

Leno has maintained that he upheld Carson's ban on Rivers out of respect for the former Tonight Show host. Jimmy Fallon invited Rivers to come on the show as one of his first guests after he took over hosting duties in 2014.
