Hilary Duff has recalled the gross revenge act she enacted on a boy who mistreated her friend as a late-teen, describing the payback prank as “spicy” and “kind of evil.”

The pop star, 39, recounted the story in a recent interview with Billboard, saying the prank was aimed at a “guy who was doing my friend real dirty” and was schemed up while her and her pal “were hitting the bottle.”

“My spiciest night is kind of evil and a long time ago, pre-children,” Duff said, before recalling the smelly concoction she dumped at the man’s house.

“We were spicy and we went and bought the cheapest, grossest can of wieners and tuna and we just had a little field day on his front lawn,” the singer said.

Duff did not reveal the identity of the friend or the unsuspecting tinned fish recipient, and was quick to clarify that the boozy drive-by occurred during her “late teen-hood” as she’s “really not a big goer-outer” these days.

Still, the singer admitted that she does still enjoy getting “real toasty with my friend.”

While the friend remains anonymous, Duff keeps a longtime circle of celebrity pals including actress Mandy Moore and fellow musician Meghan Trainor, who were thought to be the subject of Disney star Ashley Tisdale’s scathing essay about a “toxic” mom group earlier this year.

She’s not the only star to exact revenge after being mistreated.

Tiffany Haddish infamously recalled defecating in her ex-partner’s shoe after learning he had cheated, while Iggy Azalea admitted to setting her unfaithful ex-fiancé’s designer clothes alight in a bonfire.

Duff’s admission comes a few weeks after her trip Down Under for the Australian Leg of her The Lucky Me Tour, which took her to sold-out shows in Sydney, Melbourne, Perth and Brisbane.

During the Sydney show, Duff thanked Australian fans for being “so loving and so kind and welcoming everywhere you go.”

“You guys made my album go number one here. That was pretty sick. I’ll never forget that,” she said.
