Watch: Hilary Duff Recreates 'That's So Gay' PSA from 2008

Hilary Duff teamed with same-sex couple Scott Hoying and Mark Manio to recreate her 2008 PSA explaining why the phrase "That's so gay" was unacceptable (as well as lame).

Billboard reported that Hoying and Duff posted a jocular recreation of the spot on Instagram in which Hoying – a member of acapella group Pentatonix – and his fiancé played the roles of a couple of girls who thoughtlessly toss off the phrase.

The reenactment uses the original's soundtrack, with Hoying – posing with a piece of cloth wrapped around his chest – mouthing along to the sound of the actor from the original asking, "Do you like this top?"

Manio, following suit, lip-synchs the response: "It's so gay."

"You know, you really shouldn't say that..." Duff interjects. "...Say that something's gay when you mean it's bad. It's insulting."

"What if every time something was bad, what if everybody said, 'Ugh, that's so girl-wearing-a-skirt-as-a-top?'"

"Those are cute jeans though..." she quips.

"Hoying captioned the post, 'a culture-defining MOMENT!' along with a rainbow emoji," Billboard recounted, "and, frankly, he's not wrong."

"Duff has been reveling in the nostalgia of her Disney Channel days lately," the article noted, pointing out that "late last month she also gleefully reposted DNCE's acoustic cover of her 2004 smash 'Come Clean,' which was memorably used as the theme song for MTV's pioneering reality show 'Laguna Beach: The Real Orange County.'"

The callback is also fashion-adjacent enough that Billboard mentioned how "Earlier this week, the 'How I Met Your Father' star also launched her very first capsule collection with Carter's and celebrated pal Mandy Moore's baby shower."
