Jamie Foxx is receiving quite a bit of criticism on the web today after several jokes he made onstage at the iHeartRadio Awards Sunday night fell flat with viewers.

The actor took digs at rapper Suge Knight–a bold move, some might say–and at former Olympian and reality star Bruce Jenner, who has been rumored in recent months to be undergoing the transition to a female. Jenner–who is, of course, stepfather to the Kardashian ladies and has been rather high-profile due to his family’s various shows–hasn’t publicly commented on the rumors, but photographs of his altered appearance have spurred speculation in recent weeks.

“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 said.

Foxx is being called transphobic today after the jokes aired, but he has not commented.

Boo! Shame on you #iHeartAwards for allowing @iamjamiefoxx to be transphobic on national television! Those #BruceJenner jokes were wrong!!!

Jamie Foxx, if someone is potentially in the closet it's not cool to make a joke on national TV about it. Bruce Jenner joke was uncalled for

Bruce Jenner has had something of a rough year; after divorcing Kris Jenner, he’s stayed close with the Kardashian matriarch and even accompanied her to a medical procedure in a recent episode of Keeping Up With The Kardashians. However, Kris revealed that after their split, she removed his name from her living will, which upset him.

“For my entire marriage with Bruce he has always been listed as the executor on my living will. But when Bruce and I got divorced I decided that Kourtney was going to be the executor,” Kris said. “I don’t think you should be the one that would decide.”

“The problem I have with all of this–Kourtney with the final say? What, I’m not here? I’m the only one here. She’s not here,” Bruce Jenner replied.
