'Celebrity Apprentice' episode featuring Joan Rivers aired Monday night

Donald Trump was joined by a fierce and fabulous guest advisor on "The Celebrity Apprentice" this week -- the late great Joan Rivers.

"Yes, I think the coffee was brilliant. What would worry me would be they'd stop for the coffee and not understand the shoes inside. I'm a New Yorker, I mean, I'll take the coffee, get six friends and go," said Joan Rivers on "The Celebrity Apprentice."

Rivers, who was a former "Apprentice" champion herself, posthumously appeared as Trump's right-hand woman during a challenge promoting Ivanka Trump's shoe brand.

Trump tweeted about the late comedian before the episode aired, simply calling her "amazing."

But he admitted in a recent interview with Entertainment Tonight it was hard to decide whether to include her in the episode after her tragic and untimely death last September.

"Throughout history that's always been a tough decision... and she was so good we decided we'd leave it. ... I'm sure she's going to be looking down and [be] very proud of it."

Hollywood Life called Joan's appearance on the show "incredibly emotional" yet "wonderful."

And Heavy said what has been on everyone's minds for a very long time: "No one will ever compare to Joan Rivers."

We'd definitely have to agree with that one.
