Kendal Jenner was in the audience when Foxx made the joke about her father and clearly she was very uncomfortable.

Burt, Bruce's son from a previous marriage, says that if he was there he would have charged the stage if he was there and if security got to him he would have thrown something at him.

According to the site, none of Bruce's sons mind if people joke about their father adding that the LGBT community needs to chill out because it's just comedy.

Burt isn't the only person coming to Bruce's rescue, his son- in- law Kanye West apparently also wants Foxx to apologize for his joke.

On Tuesday, Hollywood Life reported that Kanye wants Foxx to apologize to Jenner as well as his daughters who were present when the singer made the joke.

"Kanye wants Jamie to publicly apologize to Bruce and his daughters," an insider told the publication. "He's tight with Jamie but taking jabs at Bruce's sexuality at an awards show, let alone one for kids, is just wrong."
