Facebook post The actress revealed on James Corden’s show how her friendship with Harris ended. They were good friends since teenagers, had the same agent and many mutual friends, but it all ended abruptly when Mayim went to see the actor while he starred in “rent”, in the late 90’s. At the end of the musical, she did not stand and clap.
She remembers that she stayed seated and noticing that Neil was staring right at her from the stage. She notes that his performance was phenomenal and everybody around her was standing, but she just didn’t feel like doing so.
When she went backstage to congratulate him, he flat out asked her the reason for remaining on her seat and that was the end of their relationship, but she says that he already forgave her by now.
