Another source apparently connected to the show, accused Trump, 70, of saying even worse during the 2009 show.
"He said: 'Why don't we fire Khloe? She is a fat piglet. Why did we get the ugly Kardashian?'."
According to the Huffington Post, the offending remarks were made off-camera.
Trump had been told he couldn't fire Kardashian simply because he thought she was "fat" or "ugly" so he instead put it down to a DUI arrest she failed to disclose.
It's not the first time Trump's remarked over a Kardashian's weight. He also commented on Kim Kardashian West during her first pregnancy, telling Showbiz Tonight:
"She's gotten a little bit large. I would say this; I don't think you should dress like you weigh 120 pounds."
