Lili Reinhart, Casey Cott, Skeet Ulrich, Hart Denton and Hayley Law walked the red carpet Thursday for the premiere in Westwood, CA.
Sprouse's girlfriend, Reinhart, wore a long, sleek silver gown and looked proud while posing alongside her leading man. The actor's twin brother, Dylan, was also in attendance.
It's been a rough week for the cast after losing Perry, who played Fred Andrews on the hit show for the past three seasons.
After news broke, several of his co-stars paid tribute to the late star on social media. Most recently, KJ Apa, who plays Fred's son, Archie.
"Rest in Love bro," Apa wrote on Thursday.
He was 52 years old.
