And as a result, they've only just made their red carpet debut as a couple, appearing together for the first time at Sunday's American Music Awards.
But the couple isn't the only thing to make its debut at the AMAs — because fans spotted that Megan seemed to be sporting some new ink on her collarbone, which likely relates to her relationship with MGK.
However, dedicated fans of the musician will know that the tattoo isn't ~that~ new. In fact, the couple made reference to it on "Banyan Tree (Interlude)," a track from MGK's album Tickets to My Downfall.
It's probably no surprise that the couple has gone so far as to get inked in honour of each other though — especially considering everything they've said about their relationship in the last few months.
