Sherri Shepherd wasn't asked to return to "Friends" after she joked about the cast's lack of diversity (read: Black people).

According to Sherri's best friend, blogger Jawn Murray, Sherri, 53, got herself blacklisted when she sent a postcard to the show's co-creator which wasn't well-received.

The former "The View" co-host sent a postcard to the show's co-creator Marta Kauffman with a joke about the show's lack of diversity.

"Sherri was one of the few black faces that was on 'Friends,'" Murray told ABC News' Linsey Davis.

"Her, Aisha Tyler and Gabrielle Union. And Sherri was on 'Friends' at a time that you sent out postcards to let people know, 'Hey, I'm going to be on TV.'"

The postcard, which Sherri sent to her friends, contained a photo of Sherri with the message, "'Friends' get a little color."

"Well, [Sherri] also sent that postcard to Marta, and she got the postcard and [Sherri] was never asked back on the show," said Murray.

Page Six reached out to Kauffman for a reaction to Murray's comments, but she didn't respond.

She did admit to not doing enough to champion diversity on the show at the virtual ATX Television Festival earlier this month.
