The couple proved they have each other's backs, showing up to the Revolve after-party following the Met Gala, which Fox attended solo.
Fox, 35, held onto her rocker boyfriend tightly as the duo made their entrance, marking the first time anyone has seen them together since MGK nearly came to blows with McGregor over an alleged DM he sent the actress.
The Transformers star showed she's team MGK, despite the drama, clutching onto him as they made their way inside the after-party in New York City on Monday evening.
Rocking a shorter version of her Bettie Page-inspired outfit, Fox looked like a million bucks in her fire-engine red mini.
Showing up to the party in an embellished Dundas one-shoulder gown, the mom of three sparkled alongside her boyfriend of one year.
Teasing her fans by showing a whole lot of leg, Fox wasn't shy about dangling her smoking hot body for all to see — and neither was MGK.
The My Ex's Best Friend rocker skipped out on the fancy $35,000 per person Met Gala to play at Central Park for a concert that ended up getting rained out.
Despite the horrible weather and officials allegedly turning off all the equipment mid show, MGK reportedly got frustrated and tried to continue on.
Meanwhile, his girlfriend was making a splash, soaking up all the attention of her first Met Gala ever.
Slipping into a scorching hot red gown with dangerous cut-outs, Fox schmoozed alongside A-listers like Rihanna, Jennifer Lopez, Ben Affleck, Justin Bieber, Kendall Jenner, and a fully covered Kim Kardashian.
She later ditched all those stars to party alongside MGK.
He wore a sheer black shirt showcasing all of his chest tattoos. Matching his rockstar look with leather pants, MGK also sported a biker jacket with red roses all over them, coordinating perfectly with Fox.
It appears the musician-turned-actor was on his best behavior inside after a drama-filled night with McGregor at the VMAs on Sunday.
As Radar reported, MGK and the MMA fighter exchanged venomous words with one another and had to be pulled apart by security. McGregor threw a punch, randomly missing.
Video shows the moment the fight went down and Fox was rushed to safety as nearby fans screamed in horror.
It was a pretty chaotic scene and when Fox showed up without MGK, many thought she had enough — but the actress proved she's in it for the long haul.
