"Apprentice" (search) lovebirds Amy Henry and Nick Warnock were "fired" last night by Donald Trump -- leaving only Bill Rancic and Kwame Jackson battling on next week's live finale for a $250,000-a-year job.

The romantic spark between Amy and Nick was extinguished quickly once they reached Trump's boardroom. Amy promptly turned on Nick -- telling Trump to fire her beau.

"Well, that's the end of that marriage," Trump cracked, calling Amy a "cold, cold person."

The four finalists were shown being interviewed by longtime Trump employees Norma Foerderer, Alan Weiselberg, Charles Reiss and Tom Downing, who then recommended to The Donald whom they thought should be axed from the NBC reality show.

First on the chopping block was Nick, the salesman from Bayonne, N.J., "who clearly doesn't present himself as an intellect," Reiss said.

Trump agreed -- firing Nick, who took his dismissal gracefully.

"I thought I was the best one there, and I was excited to have had this opportunity," he said.

The Trump group's criticism of Amy was scathing.

"She would get on my nerves after a while," Foerderer said. "Amy irritated the hell out of me," Downing said. "She reminded me of a Stepford Wife," Reiss said.

Trump took the advice to heart.

"All my executives said that there's little substance behind your words," he said to the visibly agitated Amy.

Then he fired her.

The two-hour live "Apprentice" finale airs next Thursday from 9 to 11 p.m.
