The reality personality is there to support her man who will be performing his hit "Papercuts" with Machine Gun Kelly, who arrived in a glittery red two piece suit, while his twin flame Megan Fox wowed fans in a nearly nude in a gorgeous sheer dress.
The A-List couple owned the carpet in punk-inspired looks with the Keeping Up With The Kardashians star dressed to the nines in a black leather, off the shoulder, lace-up front corset and a matching black bag.
Meanwhile, the Blink-182 drummer looked slick rocking the shirtless look in black suit pants and blazer bedazzled with silver spikes at the shoulders and knees. He accessorized with dark shades and a matching bracelet and necklace.
This hot Hollywood couple wouldn't be "them" without packing on the PDA. The duo seemed to love the attention and playfully made out to the flash of the cameras.
But their proclivity for PDA recently got them into drama with Kardashian's ex Scott Disick, who blasted her to another one of her exes, Younes Bendjima, on Instagram. The reality star DMed him saying, “Yo is this chick OK!????? Broooo, like what is this? In the middle of Italy?”
The model replied back with an icy, "Don’t matter to me as long as she’s happy. PS: I ain't your bro."
An insider recently spilled that Disick is concerned about their children, and immediately regretted sending the messages.
"He’s trying to be the best parent he can be for their kids and make it work coparenting, but he’s having problems now with Kourtney,” an insider spilled to Us Weekly. “He doesn’t think she should be showing off too much PDA because of their rated-R behavior. The kids are still young and can easily find paparazzi photos of them on their phones."
