Upper Darby's Tina Fey is not one for bad talking her former SNL cast mates, but in her 2011 book Bossypants she revealed that an unnamed fellow writer once called her a "c***."

On Monday during a press stop at the Howard Stern show, promoting her forthcoming comedy Sisters, Tina was reminded of this moment and the notorious radio host was on a mission to find out. "We have since made up," she squeaked. "I love him so much. It was Colin Quinn."

She continued, "I was trying to help him with a show that he was working on, and I think his anxiety about the writing of the show spilled over. It was very random. I was like, 'What?!' He left me a message and he said that."

Tina even wrote a 30 Rock episode called "The C Word" in which her character Liz Lemon is criticized for being too hard on her staff. "I asked Colin to be on 30 Rock like three times after that, and he turned us down every time," she told Stern. She assures the pair made up at this year's SNL 40th event. Colin even addressed it Monday afternoon.

The comedian also spoke of her late father, Don Fey, telling Stern, "I used to be afraid that would get in trouble with my dad if I did something," and proceeds to tell a story about how she's guilty of throwing around the c-word.

Sisters, starring Fey and her comedy pal Amy Poehler, hits theaters on Dec. 18.
