Megan Fox and Machine Gun Kelly made it red carpet official at the American Music Awards.

The couple, who fell for one another on the set of “Midnight in the Switchgrass” amid her secret separation from Brian Austin Green, walked the red carpet together for the first time at Sunday’s award show. She also introduced his performance.

For the big night, Fox, 34, wore an emerald green top and skirt by Azzi & Osta while Kelly (real name: Colson Baker), 30, wore a Balmain look that showed off his tattooed torso.

Kelly shared a behind-the-scenes snap with Fox, who appeared in his “Bloody Valentine” video, as well as a pic of them on the red carpet. “Slept next to a shotgun til she came into my life,” he wrote, in part.

Fox was more than happy to publicly celebrate her man. She took the stage during the show to introduce Kelly’s performance, which saw him perform “Bloody Valentine” and “My Ex’s Best Friend” and share the stage with Blink-182 drummer Travis Barker.

“Once in a lifetime, magic can happen. For this next performer, we’ve all been under his spell since his debut in 2012,” she told the crowd.
