And while the "Mirrors" singer certainly had his suit and tie on to collect his awards, many audience members wondered where his wife Jessica Biel was on his big night.
It turns out the 31-year-old actress opted to cheer her husband on from the couch.
"I'm watching from home tonight," Jessica Tweeted. "Calm down, Internet."
Jess was on hand two days earlier to support Justin at his 20/20 Experience tour stop in Tulsa. "Not a bad seat in the house. #JT2020Tour," she captioned a photo of the venue and stage.
Besides, JT clearly wasn't hurting for female company last night. Supermodel Heidi Klum posted a pic of herself hanging with Justin backstage at the show.
