Khloe Kardashian apparently isn't happy with Jamie Foxx for making jokes at her stepdad's expense.

The Keeping Up with the Kardashians star slammed Foxx during an interview on Thursday because the actor poked fun at Bruce Jenner's gender transition while hosting the iHeartRadio Music Awards this past Sunday, Us Weekly reported.

Foxx had reportedly told the audience: "We got some groundbreaking performances here, too, tonight. We got Bruce Jenner, who will be here doing some musical performances. He's doing a his-and-her duet all by himself... Look, I'm just busting your balls... while I still can."

Foxx was accused of transphobia for those jabs and then both Kardashian and Bruce's eldest son Burt Jenner spoke out about it.

"I just think it's a low blow. I think it's very mean, but you know, I wish him all the best. It is what it is," Kardashian told Yahoo's The Insider yesterday, according to Us.

"And I know Jamie, so I think that's also why that's a really low blow, but hey, guess that's what he felt the need to do for a little press."

Burt chose not to be as tactful when ranting to TMZ earlier this week about Foxx's roast-like material.

"I think he is just copying Kevin Hart because Kevin Hart is taking all his movie opportunities. He's copying him -- man's on a roll and Jamie Foxx is on the way down," Burt, the son of Bruce's first wife Chrystie Jenner, reportedly told the website.

"I would have charged the stage... If security got to me beforehand, I would've thrown something at him."
