The actor, who was recently nominated for an Emmy for his role as Tracy Jordan on 30 Rock, apparently criticised Cheri Oteri and Chris Kattan in the audio version of his memoir I Am The New Black.
According to Defamer, the 40-year-old claimed that the pair treated him "like the invisible guy".
"I could remember those two, especially those two people, treating me like the invisible guy," he said on the clip. "Now look where they at. Cheri Oteri, she can't even get arrested. Where's Chris Kattan now? They [are] never going to host Saturday Night Live."
He added that cast members Will Ferrrell, Molly Shannon and Colin Quinn treated him "beautifully," but he believed that Kattan and Oteri looked down on him.
He added: "That's what happened to me over there. They never treated me well. I never cared for them either. F**k 'em."
I Am The New Black will be released on October 20.
