TV host says Omarosa turned on him "like a viper" after he rejected her "showmance" idea.
The British TV personality wrote a column for The Daily Mail all about her use of homophobic slurs after he rejected her advance to have a "showmance" while filming the NBC show in 2008.
"I've met a lot of vile human beings in my life, from dictators and terrorists to sex abusers and wicked conmen, but I've never met anyone quite so relentlessly loathsome as Omarosa; a vicious, duplicitous, lying, conniving, backstabbing piece of work," Morgan wrote.
The tell-all comes after Morgan realized some key similarities between Omarosa's behavior on the "Celebrity Apprentice" and her current reality competition series, "Celebrity Big Brother."
"Omarosa sidled up to me at the New York Mercantile Exchange and said, quite seriously: 'Piers, do you want a showmance?' 'A what?' I replied. 'A showmance. You know, a romance on the show -- we get it on together. Happens all the time on 'Apprentice.' Everyone has sex together. Then we can make lots of money out of it," Morgan said. "I stared at her grasping, ferociously ambitious little eyes, and laughed: 'You must be joking, you deluded woman.'"
According to Morgan, the former Trump administration member turned on him "like a viper" and asked if he was refusing her offer because he is gay.
"I can honestly say I've never been spoken to in my life like the disgusting, foul-mouthed, homophobic way Omarosa spat at me throughout the weeks of filming," Morgan said. "Because I'd rejected her revolting sex plot, she decided the best line of attack was to repeatedly question my sexuality in the most crude and offensive manner imaginable."
And she didn't stop there -- Morgan wrote Omarosa also tried to tear him down by using information about his separation from his ex-wife.
"The mother of your children hates your Piers... and your children f-cking hate you, they're embarrassed by you. Is there another man raising your children?" Morgan recalled Omarosa telling him. "Shut the f-ck up, asshole. How are your kids going to feel when they wake up and discover their dad's a f-cking f----t?"
"Omarosa is a reprehensible human being, prepared to offer sex to win a reality TV show and use the most vile homophobic slurs against rival contestants. She did all this purely so it would bring her more airtime, and more attention," Morgan said.
Morgan ended his column by noting to his readers that Omarosa's time in the White House was "just as big of a scandal as Rob Porter, yet nobody seems to care."
