Megan Fox is without a doubt Machine Gun Kelly's biggest fan!
The Jennifer's Body star was all smiles as the rocker, 31, performed at Los Angeles' Greek Theatre on Friday, Oct. 15.
Fans expected nothing less from the couple, who have been open about their relationship on and offstage since they started dating last year and recently dominated social media with a sexy joint magazine shoot and candid interview. They certainly didn't disappoint.
She was photographed straddling the "Bloody Valentine" musician as he flashed a wide smile to lift her up during Friday's concert, the 35-year-old actress who finalized her divorce from Brian Austin Green the same day. That wasn't the only time they showed their admiration for one another.
According to a concertgoer who saw the couple on stage, they weren't afraid to show their affection in front of the audience. When MGK—real name Colson Baker—started singing "Candy," he walked out into the crowd to serenade Megan. This was according to an insider.
Her arms are over his neck as he sings the lyrics up close, according to the insider. A few minutes later, he takes her up and they start making out as his guitar is playing. The astute observer goes on to say, "They were probably kissing and cuddling for a good thirty seconds. It's obvious they get a rush from one other's energy, and he seemed quite happy to have her there. They were just too cute to pass up on."
The concertgoer reveals that MGK returned to the stage after their PDA-filled moment. However, according to the insider, "Megan was still the focus of everyone's attention."
The insider continues, "She was having a blast the entire show, singing and dancing along to every song." "I am without a doubt his biggest fan. An excellent show all around, with several references to her throughout the show!"
Sources say the rocker also made fun of his and Megan's recent British GQ interview, in which one of their responses spawned a viral internet meme.
According to a concertgoer, MGK was on stage and mocking the "I Am Weed" meme that was circulating around, and "essentially owned it and laughed."
When they first met, the actress told the singer, "You smell like weed," which he replied to politely. They recalled this in their conversation.
Then he looked down at me and said, 'I'm weed,'" she recalled later. That is how I can describe his sudden disappearance: "He vanished into thin air like some kind of smoke bomb."

But the good times didn't end there. On Saturday, Oct. 16, the couple hit up the hottest spot in Las Vegas, The Barbershop Cuts Cocktails at The Cosmopolitan, where they surprised guests. According to a press release, MGK and his drummer Rook surprised the crowd with a surprise appearance on the stage.
While her boyfriend performed his song "Forget Me Too," Megan "stood and danced," according to the press release."
