EXCLUSIVE: Melissa McCarthy Reacts to 'Gilmore Girls' Final Four Words, Issues 'Challenge' to Lauren Graham

The 46-year-old actress jokes that she wouldn't return to the series as Sookie St. James, but has her eye on another character.

Melissa McCarthy is still thinking about those final four words of Netflix's Gilmore Girls revival.

ET's Leanne Aguilera sat down with the 46-year-old actress at the Television Critics Association press day in Pasadena, California, on Friday, where she finally revealed her reaction to the series' much-anticipated conclusion.

"I had been waiting a long time to know, because [creator] Amy [Sherman-Palladino] had always said she knows exactly how it ends, but now it's like, 'Is that the last four words?'" cracked McCarthy, who was at the event to promote TV Land's Nobodies, which she executive produces with husband Ben Falcone.

The final four words of Gilmore Girls: A Year in the Life had been a mystery leading up to the series' conclusion. To say fans were shocked by the anticipated four words said by Rory and Lorelai Gilmore -- "Mom?" "Yeah?" "I'm pregnant." -- would be an understatement.

While the ending gave fans more questions than answers, it did leave the door open for more episodes of the beloved series, though no official decision has been made regarding the future. Alexis Bledel addressed speculation that there was a good chance new Gilmore Girls was coming, saying it "hasn't been a conversation as of yet." 

McCarthy, who came back for the reboot's "Fall" episode, says she's done with Sookie St. James -- but is willing to come back as another fan favorite.  

"No [I wouldn't come back as Sookie], but I would come back as Lorelai," she joked. "And that is a challenge to Lauren Graham."

While McCarthy works on coming back as Lorelai, the rest of the world is working on finding out who the father of Rory's baby might be -- including Milo Ventimiglia. 

"I don't think it's any of the three guys at all," the This Is Us star told Variety on the Golden Globes red carpet on Sunday. "I don't know. You know what, I haven't really sat around and thought about it, wondered who it was, so I'll be as surprised as anyone else is."

Netflix, meanwhile, has enjoyed keeping the guessing game going, teasing fans with a cryptic tweet last month.
