If there's anything that can bond co-stars, it's surviving the child star curse. 

How I Met Your Father's Josh Peck and Hilary Duff have both done just that, with the Drake & Josh and Lizzy McGuire alums formed what he called a "surreal" bond after they met on the set of the 2009 movie What Goes Up. 

"It is a very specific experience that only her and I can really speak to," Josh told E! News of his connection with Hilary. "Having been the attendees of a weird and exclusive high school, it's cool to reminisce and to have that sort of shared experience."

Aside from their respective careers as child stars, Josh and Hilary have bonded over parenthood. Hilary has three children—10-year-old son Luca, whom she shares with her ex-husband Mike Comrie, and daughters Banks, 4, and Mae, 22 months, with husband Matthew Koma—while Josh and his wife Page O'Brien Peck have two sons: Max, 4, and Shai, who was born in October 2022. 

"Kids are our happy place," Josh, 36, said. "It's where we just feel most comfortable."
