Barker's Instagram post featured a mirror selfie of the pair — with the TikTok star flipping off the camera — as well as a video of her dancing in a bedroom, another selfie from a silly underneath angle and a sweet photo of the pair side-by-side.

He also shared photos of D'Amelio dressed for an event, smiling in bed and posing alongside Barker, as well as a video of her dancing in sweats at home, a picture of her smiling on the ground and a snap of the pair at Disneyland.

Barker, who is Blink-182 drummer Travis Barker's son, and D'Amelio went public with their relationship in July 2022 after sparking romance rumors with a public spotting at his father's concert the month prior.

A source told PEOPLE later in July that the budding romance between the two Gen Z stars — dubbed "Chardon" by TikTok users — was in its "early stages."

Last month, D'Amelio and Barker appeared on the cover of Mini V — a youth-focused version of the fashion magazine V. This marked the couple's first magazine cover together.

For the feature, the lovebirds answered questions from the Proust Questionnaire, a 19th-century game created by Marcel Proust, letting readers in on what makes them the happiest, which just so happened to describe moments like these.

Barker answered the question, "What is your idea of perfect happiness?" with the answer, "I don't know if perfect happiness truly exists, but if it did, it would be me creating art, surrounded by friends and family."

He answered: "Humor for sure. I'm constantly cracking jokes and I love being around people that do the same! A quality I especially admire about Charli."
