Breakfast at 1 a.m. is never too late when you're in love!

On Saturday, Lili Reinhart shared an adorable Instagram pic taken by her main man Cole Sprouse and it's got us all glowing.

The too-cute photo shows the Riverdale actress smiling at a late night eatery as she jokingly tries to brush away a shutterbug. The actress tagged the photog as her co-star and boyfriend, whom she has been linked to since July.

Sprouse, who is an avid photographer, appears to have snapped his lady love just after a bite of breakfast. 

Along with the sweet image, Reinhart wrote, "When I wanted eggs and toast at 1am."

E! News confirmed that two were dating after the co-stars-turned-more first went public during 2017 Comic-Com. Reinhart and Sprouse have appeared on each other's social media accounts on more than one occasion since news hit that the duo took their love off the small screen and in to real life. 

On the hit CW show, which is currently in its second season, Reinhart appears as Betty Cooper and Sprouse takes on the role as Jughead Jones. The two are an unlikely (but fan-favorite) couple on the show and are lovingly called "Bughead" by their loyal fans.
