Colin Jost could be ready to leave Global’s “Saturday Night Live”.

The head writer and star of the long-running sketch comedy show teased his possible departure in his new memoir A Very Punchable Face, and fans are losing their minds.

In an excerpt obtained by Variety, Jost reveals he’s “preparing mentally” to leave “SNL” in the near future, but plans to continue co-anchoring “Weekend Update” with Michael Che through the U.S. 2020 Presidental election.

According to Jost, he has a desire to try his hand at developing bigger and broader ideas.

Hi everyone. I spent the last three years writing a book and it’s coming out April 14. It’s called “A Very Punchable Face” based on the fact that several of my close friends have told me, “You have a very punchable face.” I’m really excited about the book and I hope you’ll read it. I promise it’s a quick read and largely non-inspiring. Just stories from my life and from SNL that I thought were funny or uniquely disturbing. And I get physically injured or maimed in many of the chapters which I’ve discovered is how people most want to see me. There’s a link in my bio if you’d like to pre-order the book. It’s the perfect gift for birthdays, holidays, weddings, divorces, first communions, and hostage situations gone awry.

Fresh from graduating from Harvard University in 2005, Jost joined the writing team for “SNL” and has changed his title over his 15 years on the show, starting off as a writer before being promoted to head writer and member of the show’s cast. Jost has been co-hosting “Weekend Update” since 2014.

“SNL” returns Feb. 29, with host John Mulaney and musical guest David Byrne, at 11:30 p.m. ET/PT on Global.

Daniel Craig is also set to return to the “SNL” stage on March 7 with musical guest The Weeknd.

A Very Punchable Face drops April 14.

However, a source tells ET that this is not true.

In addition, rumours of “SNL” cast shuffles appear every year about this time, and Jost’s departure is neither imminent nor confirmed. Furthermore, the source of Variety‘s report isn’t the published book, but an uncorrected memoir that may still be changed.

Regardless of Jost’s intentions, here’s a sampling of how Twitter has been reacting to reports of his potential exit:
