The “Scooby Doo” actor cheekily reminded her Instagram followers of an interview Stern conducted with Prinze around two decades ago.
During the chat, Stern tells the actor, “So, you will marry Sarah Michelle Gellar even though you know that it won’t last?”
“Oh, absolutely it will last!” Prinze responds.
In the back and forth, the radio host adds, “it’s not gonna work for you,” before making his big prediction.
“I wanna make a written bet with you,” Stern says. “In about 10 years, you’re gonna hunt me down and go, ‘Howard, I owe you money.’”
“We’ll do a written bet,” Prinze answers, while Stern talks about “a million dollars.”
“We’ll do it right now,” the actor says, while Stern answers, “See, for a million, I’d stay married.”
Now, Gellar is coming to collect her money — as the couple has surpassed the Sirius XM host’s expectations by many, many years.
The actor reposted screenshots from Prinze and Stern’s interview on her Instagram Story and tagged the radio host, writing “What do you think?!?”
In an additional story with screenshots of the talk, she added, “I think you owe us.”
Prinze reposted the stories on his own Instagram, writing, “She will not forget” with two laughing face emojis.
He hasn’t forgotten, either, as the cookbook author brought up Stern’s bet in 2016 during an interview with AOL Build.
“I did ‘The Howard Stern Show’ when I was a young buck, and he was cracking jokes that, you know, me and Sarah were just sleeping together and we’d break up in a few years,” he said.
“And he bet me a million dollars that we would break up in under five years,” Prinze added, before pointing and speaking directly into a camera.
“You have not paid that bet, young man,” Prinze said, as the audience laughed.
Prinze and Gellar met in 1997 while filming the movie “I Know What You Did Last Summer” before tying the knot in September 2002. They now have two children, Charlotte and Rocky.
