In late September 2014, discussions arose that Lohan had pitched an idea to Fey for a sequel. Later that year, Lohan, along with other cast members of the original film, asked Fey to write a screenplay for it. The idea was brought up during a 10th anniversary for the film in "Entertainment Weekly", with Fey declaring she regretted not doing a sequel closer to its original release: "At the time we did want to start the conversation about the sequel, and for whatever reason I was like, 'No!!! We shouldn’t do that!' Now I look back and I'm like, 'Why?' But now, no—it’s too late now." Seyfried had previously stated she was "really willing to pursue" a sequel and was unsure why it had not happened. In December 2016, Lohan mentioned she was still trying to pitch a sequel, with the hopes of Jamie Lee Curtis and Jimmy Fallon appearing in the film. She stated she knew Fey, Michaels and Paramount were busy, declaring: "I will keep forcing it and pushing it on them until we do it." In October 2018, Seyfried said people needed to start a campaign for it to finally come into fruition. In January 2019, Lohan was interviewed by Howard Stern who wondered whether the sequel would ever happen. Lohan repeated her interest in revisiting the role and confirmed she had spoken to Fey about it, also saying sequel plans were not currently in the works, "I think they can't do it right now. I've spoken to her but it can't happen without her and all of the cast. [... Sometimes you're like, 'It's just too soon to do it.' But it's been 15 years." In October 2019, Chabert was asked if a sequel would be happening to which she replied: "I don't know. I wish I had an answer for you, I feel like you need to start a petition," while saying she would "of course" revisit the character if given the chance as "it would be so much fun to revisit these women and see where they are now."
