Christina Applegate Reveals She's Working on a Memoir: 'I'm Writing It Right Now'

Christina Applegate is ready to put pen to paper!

Applegate, 52, revealed that she's working on a memoir while chatting with her Anchorman costar, Will Ferrell, on the Tuesday, July 9 episode of her and Jamie-Lynn Sigler's MeSsy podcast. July 9 is the 20th anniversary of Anchorman: The Legend of Ron Burgundy.

The Dead to Me star made the surprise reveal as Ferrell, 56, discussed his beloved 2000 Saturday Night Live sketch "More Cowbell," which featured the likes of Christopher Walken and Jimmy Fallon.

"I've watched Saturday Night Live since I was little, which I probably shouldn't have been watching, but I was raised by Nancy [Priddy]," she said before taking a pause and saying with a slight chuckle, "It's gonna be in the book."

After Ferrell advised her to "wait for the book," Applegate added, "Oh yeah, no, I'm writing it right now." and went on to praise the SNL skit.

"I just think like, I don't think there are many, I could name like five sketches that have, like, made me crack up over and over and over again," she told Ferrell. "And I'd say out of those, you're in most of them, obviously. And like Cowbell and the cheerleaders, I mean, I can't, I can't."

The news comes as no surprise as Applegate, who revealed she was diagnosed with multiple sclerosis in August 2021, previously opened up to PEOPLE about how discussing her life journey has been therapeutic for her.

"We have each other, and that's helped us so much. We would talk on the phone for two hours, and we'd be laughing and crying and we were like, 'This is helping us. Let's record this. Let's do it,'" she said about her podcast in March.

Sigler, 43, who is also living with MS, echoed similar sentiments, telling PEOPLE that the podcast has allowed them to figure out "how to still push through."
