Lindsay Lohan Was 'Very Hurt and Disappointed' by a Joke Included in New Mean Girls Movie

Lindsay Lohan wasn't on board with a joke included in the new Mean Girls movie musical.

The actress, who starred as Cady Heron in the original 2004 film, joined writer and former costar Tina Fey at the New York City red carpet premiere to support the new film last week, and (spoiler alert) she turns up in one scene for a surprise cameo.

However, a rep for the actress tells PEOPLE that Lohan, 37, was not a fan of the new Mean Girls movie having a line of dialogue mentioning "fire crotch."

"Lindsay was very hurt and disappointed by the reference in the film," her rep says.

A spokesperson for Paramount did not immediately respond to PEOPLE's request for comment.

In the movie, Megan Thee Stallion, who also contributed a song for the soundtrack, shows up in social media montages. At one point, the rapper says about Cady (played by Angourie Rice) and her Christmas-themed talent show outfit, "Y2K fire crotch is back."

The reference is an apparent nod to a 2006 paparazzi video in which Brandon Davis referred to Lohan as a "fire crotch."

Fey, 53, reprises her role as Ms. Norbury along with returning as screenwriter and producer of the new Mean Girls film. The Saturday Night Live alum told Entertainment Weekly about making Lohan's cameo happen.

"Paramount was like, 'Can you get any of the original ladies? And I was like, 'I can't fit five people in.' I felt like if I could only get one person as a surprise, the original movie is really Lindsay's movie," said Fey. "As great as they all are, she's the heart of that movie."

"And I thought, well, what could she do? I didn't think [she should] play a teacher. I was trying to think of something that you wouldn't expect," she continued. "And just to have her do that late in the movie, it also feels like it comes, I hope, at a time where fans weren't expecting one more little surprise. It also lets her be smart, which Cady is."

Fey also told The New York Times about eliminating some jokes from the new Mean Girls after the dialogue proved problematic in the 20 years since the original hit theaters.

"I was writing in the early 2000s very much based on my experience as a teen in the late ’80s. It’s come to no one’s surprise that jokes have changed," she said. "You don’t poke in the way that you used to poke. Even if your intention was always the same, it’s just not how you do it anymore, which is fine."

Added Fey, "I very much believe that you can find new ways to do jokes with less accidental shrapnel sideways."

Rice, 23, spoke to PEOPLE about sharing screen time with Lohan in the new film, saying it "meant so much to me."

"It is such a rare experience to really get in the head of a character and then meet someone who's done the same thing. Just to have that shared experience, it means a lot," she said. "Sometimes acting can be a lonely job. You get in the head of a character and then you have to say goodbye to it, and you feel like you've abandoned it."

"But to know that Cady has been a part of so many actors' lives and so many actors have delved into that character — she's bigger than the actor in a way," Rice says of the character, also played by Erika Henningsen on Broadway. "It means a lot that I get to share that with so many special performers, especially Lindsay."

Mean Girls is in theaters now.
