On Saturday, Dec. 4, the couple celebrated the launch of MGK's new nail polish brand, UN/DN LAQR, in West Hollywood, Calif. with a unique accessory linking them together all night: thin, silver chains attached to both of their pinky fingernails.
Both Megan and Machine Gun Kelly—real name Colson Baker—wore similar outfits to the event, donning all-black ensembles and fitted blazers to let their bright pink nail art take center stage.
Other celebrities who attended the night included rocker Avril Lavigne and TikTok stars Charli and Dixie D'Amelio and Chase Hudson.
This isn't the first time the Jennifer's Body actress and the "Forget Me Too" singer have shared a major fashion moment together. In October, the lovebirds graced the front cover of British GQ Style's autumn/winter issue with a steamy photoshoot that featured Megan almost entirely naked and pointing a gun at a long-haired Machine Gun Kelly.
"I always had a streak of that when I was young," she said. "He has elevated that a lot and brought that out a lot more."
She also revealed that he takes fashion cues from her as well, especially "when we're going back-and-forth between what we want to wear" or "how he wants to be for couture."
He added, "[UN/DN LAQR is] the Willy Wonka of what beauty is to become."
