Cole Sprouse and Lili Reinhart usually keep their relationship out of the spotlight, but they recently gave us a tiny glimpse of their bond as they attended the premiere of Cole's new film, Five Feet Apart. On Thursday, the couple showed rare PDA as they walked the red carpet together. The Riverdale costars looked blissfully happy as they cuddled up for a few photos and stared into each other's eyes. At one point, Lili even leaned in to give her boyfriend a sweet kiss on the cheek. Even Cole's costar, Haley Lu Richardson, couldn't help but fawn over the two as she ran up to Lili and chatted with her on the carpet. Now if you don't mind, I'll just be staring at these adorable photos with a stupid grin on my face for the rest of the day.
