Megan Fox and her Machine Gun Kelly beau stunned onlookers with their X-rated red carpet PDA when rocked up at the Billboard Music Awards.
However, things took a turn later in the evening as a video emerged of Megan appearing to swear at her beau.
In the clip, Megan appears to mouth 'What the f***' while speaking to Kelly, who is standing next to her.
Megan looked annoyed in the video and appeared to be speak to a third person before leaving the scene.
Earlier in the night, the Transformers actress, 35, and Bloody Valentine singer, 31, literally couldn't keep their hands off each other as they were seen making out on the red carpet.
Fox was oozing sex appeal wearing a risque black Mugler cutout dress which highlighted her cleavage and toned abs while Kelly opted for a shirtless black tuxedo revealing his tattooed torso.
To add an edgy vibe MGK opted to have his tongue painted black for the event which saw him collecting the award for Best Rock Album.
He landed a smooch on Fox before heading up again to receive the award for Top Rock Artist at the star-studded ceremony.
Fans of MGK were given a behind-the-scenes access with his Instagram Story following his 'messy hair cut' and tongue painting preparations.
The couple first hooked up in May 2020 after meeting on the set of Randall Emmett's directorial debut, Midnight In The Switchgrass.
Fox is currently locked in a custody battle for her and former husband of 10-year Brian Austin Green, for their three children.
While Kelly is also a parent to 12-year-old daughter Casie from a previous relationship.
Upon collecting this Billboard Award the musician gave a special shout-out to Megan by saying 'my twin soul shows me love.'
MGK also encouraged people in the crowd to keep doing what they love by sharing, "If five years, 10 years, 12 years would have been too long waiting for this moment, then I wouldn't be having this moment.
"So, just show the universe it can't take your dream from you."
