Charles Michael Davis
This smoldering hottie had a "will they, won't they" relationship with Hilary Duff's character on Younger. Yet competitive Zane (Charles Michael Davis) couldn't handle Kelsey's (Duff) success at Millennial Imprint. Could Zane and Kelsey get their true happily ever after on How I Met Your Father? Even if he's not the father, we'd just be happy to see them together again.
Matthew Koma
Hilary Duff's real-life husband would make for the sweetest cameo in her new series. While Matthew Koma isn't an actor (yet) he is a famous musician known for collaborating with Shaina Twain, The Knocks, and Zedd.
Christopher Mintz-Plasse
McLovin' still has more love to give. Christopher Mintz-Plasse counts Hilary Duff as a real-life pal—he even officiated Duff's wedding to Matthew Koma! Koma and Plasse are BFFs, so why not have them both appear on Duff's new series?
Chad Michael Murray
Princeton can wait: we're still shipping Sam (Hilary Duff) and Austin (Chad Michael Murray) from 2004's A Cinderella Story. Let's just not have Murray reprise his Riverdale role as a cult leader and we'd love for him to win Sophie's heart on How I Met Your Father.
Clayton Snyder
Just in case you needed a reminder of Lizzie McGuire's middle school crush Ethan (Clayton Snyder), it's clear they're still pals IRL. Snyder even took Hilary Duff to his middle school dance! "I can't say she had a great time, but she's a great sport for going," Snyder previously joked of inviting his teen A-list co-star to his school. Who wouldn't want to see that be recreated in How I Met Your Mother? Sign up Snyder for a role as a middle school teacher, and it's a full circle love story.
Oliver James
Fans need to Raise Your Voice to get Hilary Duff's 2004 onscreen love interest to return to Hollywood. While Oliver James—who also is beloved for his role in What A Girl Wants opposite Amanda Bynes—hasn't acted since 2012, but we have a feeling Duff might be able to convince him to come out of retirement.
Tom Welling
Ok hear us out: Tom Welling is too hot to just play Hilary Duff's sibling in Cheaper By the Dozen. It's a throwback, but one we're definitely here for.
Regé-Jean Page
It hasn't not been proven that Regé-Jean Page left Bridgerton to be on How I Met Your Father. Seems legit, and we know Sophie (Hilary Duff) wouldn't be able to resist the Duke's burn for her.
Zac Efron
The High School Musical hunk can return to his Disney Channel roots opposite Hilary Duff. And yes, we want Zac Efron to be in every show, movie, commercial...anything to see him onscreen.
Frankie Muniz
Lizzie McGuire viewers remember Frankie Muniz playing himself on an episode of hit Disney Channel series. But die-hard Frankie fans know that Hilary Duff also starred alongside him in Agent Cody Banks. Their reunion would be a heavenly gift for any former 2000s tween!
Josh Radnor
The OG How I Met Your Mother star would be a great fit for Hilary Duff's spinoff. Plus we just want to see Ted Mosby again!
Yani Gellman
Paolo, is that you? Last time we checked, teen heartthrob Yani Gellman is still acting long after The Lizzie McGuire Movie. His last TV role was in Bosch in 2019, so we know he's just waiting for Hulu's call.
Adam Lamberg
Reboot be damned, we still want to see Gordo (Adam Lamberg) and Lizzie McGuire (Hilary Duff) together as adults!
