Jamie Foxx is in hot water after making a joke about Bruce Jenner's alleged transition into a woman at the iHeartRadio Music Awards on Sunday night.

That awkward, nearly silent response probably wasn't exactly what Foxx was hoping to get from the audience there.

Viewers on social media were anything but pleased with Foxx's comments, with some even accusing the actor of transphobia.

Jenner's youngest daughter, Kylie, was scheduled to make an appearance at the show, but it's unclear whether she showed up.

Jenner has yet to comment on the alleged gender transition. But he will reportedly address it on this season of his family's reality show, "Keeping up With the Kardashians." (Video via E! / "Keeping Up With the Kardashians")

As of late Sunday night, there has been no comment from Foxx, iHeartMedia or Jenner.
