Model and actress Jenny McCarthy is under fire after posting a joke about transgender people online while poking fun at a scandal surrounding Jennifer Lopez’s boyfriend, Casper Smart.

The “On the Floor” hit maker’s dancer beau has been at the center of controversy after reportedly cheating on his superstar girlfriend with a transgender bikini model.

On Tuesday, McCarthy decided to weigh in on the rumors, and took to Twitter to write, “Did Jennifer Lopez’s boyfriend cheat on her with a transsexual model? I heard JLo gave him an ultimatum: ‘it’s either me or her/him’”

The TV personality soon deleted the tweet after receiving a barrage of responses criticizing her for the joke.

Author Kelly Oxford wrote, “Hey @JennyMcCarthy your last tweet was really transphobic. I’m a ‘learn and be better’ type, so I thought I’d let you know. PEACE.”

McCarthy has yet to comment.
