Stewart recently singled out Grant as the worst guest in the history of The Daily Show for a 2009 appearance in support of Did You Hear About the Morgans?
"He's giving everyone s**t the whole time, and he's a big pain in the ass. And we've had dictators on the show," Stewart joked. "[Hugh kept asking,] 'What is that clip? It's a terrible clip'. Well, then make a better f**king movie!"
Grant has since taken to Twitter to admit that he acted inappropriately during his Daily Show interview.
"Turns out my inner crab got the better of me with TV producer in 09. Unforgivable," the actor wrote.
He added: "J Stewart correct to give me [a] kicking."
Grant's Daily Show appearance in 2009 was his very first interview on the Comedy Central series.
The Daily Show airs Mondays through Thursdays at 11pm ET.
