Sprouse and Reinhart, 22, were together at the event to promote The CW television show Riverdale that they both star alongside in.
It has been reported that the pair did not spend much time together while at the event. However, they are still friendly enough to have sat next to each other on the panel.
Fittingly, the world first found out about the co-stars becoming official when they were spotted kissing at Comic-Con event in July 2017.
In March this year, Cole opened up about his relationship with Lili, and it was heartwarming.
Cole described to Glamour Magazine the romantic date he took Lili, on surprising her with a hot air balloon ride.
“I really like the road-trip date. I took my girlfriend on a date where we drove to this location deep into Canada, and I surprised her with a big hot-air balloon adventure, which was quite a bit of fun. I like traveling quite a bit. I like road-tripping. Those grand experiences always end up yielding the greatest memories—and the greatest romances.”
Cole often used Lili as his muse when he was practicing his photography too, posting gorgeous photos of her on his Instagram.
