Megan Fox and Machine Gun Kelly make their red carpet debut at 2020 AMAs

Megan Fox marked a major relationship milestone on Sunday with “twin flame” Machine Gun Kelly.

The couple of nearly six months made their red-carpet debut at the 2020 American Music Awards, where Fox, 34, introduced Kelly, 30, who performed with 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,” Fox said during Kelly’s introduction. “Performing ‘Bloody Valentine’ and ‘My Ex’s Best Friend,’ joined tonight by Travis Barker, it’s Machine Gun Kelly.”

Fox, who first met Kelly while filming Randall Emmett’s “Midnight in the Switchgrass,” appeared in the music video for “Bloody Valentine” in May. Her split from husband Brian Austin Green, 47, was also confirmed that month.

Fox and Green had been married since 2010 and share three sons together: Noah, 8, Bodhi, 6, and 4-year-old Journey.

In September, Kelly proclaimed he fell in love for “the first time” with Fox.

“I didn’t know what [love] was until me and her made eye contact,” Kelly said on the “Howard Stern Show.” “That’s when I was like, ‘Whoa.'”

“It was my first experience with being open to love and stuff like that,” he said. “I definitely wasn’t set up to believe that that’s something that could ever exist.”
