Chrissy Teigen has a very important PSA.

The “Cravings” cookbook author shared her proposal for a widespread social media curfew as TikTok made headlines over the weekend with a dramatic shutdown that barely lasted 12 hours.

“I personally think that one day there will be the most incredible rule, my first rule would be — I think the government or some kind of ethics committee, somebody, should shut off social media between 6 p.m. and 6 a.m.,” Teigen said via her Instagram Story Saturday night.

“Leave it all up. Everyone gets to do anything they want but only between 6 a.m. and 6 p.m. Shut it off. Done.”

The Sports Illustrated Swimsuit model, 39, who explained her stance while talking to the camera in bed, went on to reminisce about life before social media.

“I come from the days where we had nothing and then we saw something. Guys, life was great. Life was awesome before this,” she continued.

“I know it’s hard to see it now, but it’s doable. It’s very doable,” Teigen argued. “This doesn’t have to be our lives. And I say this for myself as well because, obviously, I’m on here right now doing this! But it doesn’t have to define us or be our whole lives.”

Teigen’s comments came as celebrities such as Kourtney Kardashian, Lizzo and Heidi Montag mourned TikTok before the platform briefly went dark Saturday night.

Amid the shutdown, more than 170 million Americans were blocked from using the Chinese-owned app — whose parent company, ByteDance, had previously been given until Jan. 19 to sell its US business.

Users were met with a message that read in part, “Sorry, TikTok isn’t available right now. We regret that a U.S. law banning TikTok will take effect on January 19 and force us to make our services temporarily unavailable.”

However, the app was up and running again by Sunday morning.

TikTok praised President-elect Donald Trump — who will be inaugurated Monday — as they confirmed they were in the process of restoring service to American users.

“We thank President Trump for providing the necessary clarity and assurance to our service providers that they will face no penalties providing TikTok to over 170 million Americans and allowing over 7 million small businesses to thrive,” TikTok Policy wrote in a statement posted via X.

“It’s a strong stand for the First Amendment and against arbitrary censorship. We will work with President Trump on a long-term solution that keeps TikTok in the United States.”

Following the sudden turn of events, policy expert Joel Thayer, a DC-based tech lawyer, suggested the shutdown was likely a “PR stunt.”

“TikTok’s early shutdown either came down to corporate incompetence or a deliberate PR stunt to encourage a manufactured sense of panic,” Thayer told The Post Sunday.

“Given it’s waffling, I’m assuming it’s the latter.”
