Simple Plan are writing their seventh studio album — and they have TikTok to thank for the timing.

Drummer Chuck Comeau told Billboard the band has started work on the follow-up to 2022’s “Harder Than It Looks,” with writing continuing into 2027. No release date is set yet. But the reason the band is suddenly reaching a whole new generation has nothing to do with new music — it’s a song from 2002.

“I’m Just a Kid” has gone viral on TikTok, soundtracking a challenge where users recreate their childhood photos. Comeau called the revival a “gigantic gift.” Some crowds now include fans who weren’t even born when the song came out — standing next to original fans who are bringing their own children to the shows.

The band is leaning into that full-circle moment. They’ll release the children’s picture book “I’m Just a Kid: The Story of Simple Plan,” illustrated by Jomike Tejido, on March 9, 2027. Next year marks 25 years since their debut album, “No Pads, No Helmets… Just Balls.” A special-edition vinyl and a few anniversary performances are on the table — but not a full album tour.

They’re also headed to Australia for the Good Things Festival — Dec. 4 in Melbourne, Dec. 5 in Sydney, Dec. 6 in Brisbane — on a bill led by Limp Bizkit and also featuring Spiritbox, the All-American Rejects, Bad Religion, and MxPx.

And for anyone wondering about a farewell tour: Comeau said it’s “not in the cards for now.”

For the record: 2004’s “Still Not Getting Any” debuted at No. 3 on the Billboard 200, “Perfect” hit No. 24 on the Hot 100, and “Welcome to My Life” reached No. 40.
