The Riverdale actress took to Instagram Friday with a sweet note dedicated to her co-star, who E! News confirmed just weeks ago are dating.
"To the man who has showed me more beautiful places in this past year than I have ever seen in my whole life," she wrote alongside an artistic photograph of Sprouse looking out over a city skyline. "Happy birthday, Cole. Thank you for all of the adventures and here's to many more."
Not a bad way to turn 25, huh?
