Cole Sprouse and Lili Reinhart might be Hollywood's most mysterious and private couple — they're also the most in demand, thanks to their ardent young fans who can't help but swoon at their on-screen Riverdale romance. The pair met and ~secretly~ started dating around the same time their respective TV characters, Jughead Jones and Better Cooper, started dating on the hit CW show. 

Sprouse and Reinhart actually never verbally confirmed their relationship, but the pair finally began making appearances as a duo and posting adorable tributes to one another on social media last year, and thus Sprousehart was officially born! 

And since the couple made their hesitant debut, they've been getting even more and more publicly affectionate, much to fans' delight. Their latest red-carpet appearance for Sprouse's new film, Five Feet Apart, certainly proves so.

Cole Sprouse and his Riverdale costar-slash-IRL girlfriend Lili Reinhart looked so cute together at the premiere for Five Feet Apart.

The two of them rarely appear in public together, let alone participate in public displays of affection. So when they did BOTH at the SAME TIME, fans lost their minds. If you didn't ship them or even their Riverdale characters before, you probably do now.

Reinhart shared an adorable photo from the red carpet with a sugary sweet caption to match.

Reinhart took to Instagram to praise Sprouse and his Five Feet Apart costar Haley Lu Richardson.

"I am so in awe of @colesprouseand @haleyluhoo for their work in this film," she shared. "The last few days have been hard on all of us... and this film touches you in a way that makes you feel incredibly grateful to be with the people you love. I can’t express enough how moved I was by @fivefeetapartfilm — I can’t wait for the world to see it."

The couple has always been extremely private, so this adorable appearance was unexpected on all fronts.

The two of them are barely seen in publicly together period, really. They don't usually walk red carpets together, and they definitely don't talk to the press about their relationship. In fact, we kind of just had to assume they were dating in the first place. They never officially acknowledged dating rumors and clearly don't need to anymore.

Sprouse once even told People that he would never officially "confirm" their relationship.

And he gave a good explanation as to why. In the interview, Sprouse said he didn't want to give people "more power" over their relationship with a confirmation or denial. He feels many people who are just too invested in the personal lives of others and that giving them the information they want just encourages them. "Going to college made me realize you have to have real spaces of privacy and you have to establish those early," Sprouse said.

Back when their relationship was a (pretty solid) rumor, they avoided going anywhere near each other when at the same event.

Sprouse and Reinhart were only rumored to be dating back in August of last year. At that time they appeared on the red carpet for the Teen Choice Awards with the rest of the Riverdale cast. They noticeably did not walk together, though. In fact, they made sure to leave an entire empty seat between them during the ceremony. Clearly, that was a little bit of overkill.

The couple didn't make their red-carpet debut until the 2018 Met Gala.

Their first red-carpet appearance as a rumored couple was in May of last year. This is a huge marker in the couple's relationship that gave way to all the PDA we're seeing between them now.

And since then, they've been extremely affectionate on social media. They've basically given up the guise of being in a secret relationship.

Take this post from Reinhart's Instagram. In a caption of a post she shared for Sprouse on his 26th birthday, she called him "my love." She even said that their relationship is a "beautiful adventure."

"It seems as if the world would still be a stranger to me, if not for you. I’m so thankful that our paths intertwined to form this beautiful adventure," the post read.

Sprouse has even referred to Reinhart as his muse.

Another one just for good measure

Sprouse's Instagram is full of his own professional photography, and there are plenty of shots of Reinhart on there. In one of them, he called her "the only thing keeping me sane." On her birthday, he posted a shot of her that's not exactly safe for work. The caption read: "Both the birthday and the gift. My little muse, happy birthday my love." 

Reinhart also referred to Sprouse as her "love" back in July, too.

Long story short: BUGHEAD LIVES, Y'ALL.

On the show AND in real life. Really, how much better could both of these love stories get?
