The 40-year-old actor and 36-year-old actress, who played unlikely love interests Zack Siler and Laney Boggs in the 1999 movie, got together for coffee in Los Angeles.
"When the homie @RachaelLCook wants to have coffee, you get some damn coffee! #OldFriendsNewFriends," Prinze captioned a photo of himself with his former co-star.
She's All That proved to be one of the most popular teen movies of the 1990s, earning $103 million on a $10 million budget. Prinze and Cook had reflected on the film fondly in an interview with The Daily Beast for the movie's 15th anniversary.
"People [still] tell me, 'Hey, I loved that movie!'" the actor revealed. "It's more for the outcasts. When our movie first came out, a lot of people went teenybopper crazy, but a lot of people also came out and said, 'That was me, man.'"
"I always feel like I'm on Candid Camera when I'm in the drug store of something and 'Kiss Me' comes on, because I think it subliminally triggers memories from the movie for people, so then you get the, 'Do I know you from somewhere?' from the cashier," Cook said.
Prinze and Cook have both since voiced characters on the Adult Swim series Robot Chicken. The actor presently hosts the game show First Impressions, while Cook will star in a new adaptation of A Midsummer Night's Dream.
