Happy Birthday, Cole Sprouse!
On Friday, the Riverdale star turned 25 and got a lot of birthday love from his co-stars -- especially Lili Reinhart, who had the sweetest things to say about her on-screen beau!
"To the man who has showed me more beautiful places in this past year than I have ever seen in my whole life. Happy birthday, Cole. Thank you for all of the adventures and here's to many more ?," the actress wrote on Instagram, alongside a snap of Sprouse surrounded by greenery and skyscrapers in the distance.
K.J. Apa also took to Instagram to share a pic of Sprouse, writing, "One for the books. Ps happy b day love ya heaps bro."
Meanwhile, Madelaine Petsch and Casey Cott poked fun at their co-star by writing silly captions on their Instagram pics.
"The only day I'll let you get more attention than me... (who am I kidding that's everyday) happy birthday turd ?," Petsch wrote, while Cott captioned his pic, "Happy birthday. You're welcome for the followers."
