Comedienne Joan Rivers revealed she once ditched a joke about First Lady Michelle Obama from her stand-up routine - because she feared she'd be accused of racism.
Recalling the wisecrack to shock Jock Howard Stern, the comedy legend said: "We used to have Jackie O now we have Blackie O!"
The audio can be heard here on RadarOnline.com.
Rivers wrote the quip about President Barack Obama's wife in reference to her fashionable dress sense and comparing her to former First Lady Jackie Kennedy Onassis.
"I thought it was a funny complimentary joke when she first came (to the White House)," the 77-year-old comedienne told Stern.
"I think it's an adorable joke... I thought it was a compliment!"
In the interview, Stern and his sidekick Robyn Quivers laughed yet questioned whether Rivers' joke was racially-motivated.
"Where's the compliment in that? I'm looking and looking, I'm trying to find it," Quivers asked Joan.
"They said you can't say that," Joan admitted.
Rivers is starring in a new reality show Joan Knows Best on Tuesday on WE TV at 9pm.
