Jamie Foxx hosted the second annual iHeartRadio Music Awards Sunday night in Los Angeles. In his opening monologue, Foxx joked about Olympic gold medalist Bruce Jenner and the athlete’s rumored transition from being male to being female.

“We got some groundbreaking performances, here too, tonight,” the Academy Award winner said. “We got Bruce Jenner, who will be doing some musical performances. He’s doing a his-and-her duet all by himself.”

Foxx continued: “I’m just busting your balls while I still can.”

Foxx’s insensitive material has drawn widespread criticism; Jenner has not yet spoken publicly about a possible transition.
