The pop superstar has had a whirlwind past few weeks, after embarking on the 'Legends of the Summer' tour across America with rapper Jay-Z and putting on a show-stopping performance at the MTV VMAs last month, which even saw him bring together his former group 'N Sync for a one-off reunion.
But there's no slowing down in Justin's world, as he boarded a plane and flew over to our side of the pond this week for the GQ Man Of The Year Awards yesterday (3 September), where he presented the gong for Best Designer and hung out with some of his Hollywood pals.
Justin, 32, looked extremely dapper for the ceremony in a black three-piece suit, which featured a subtle design on the jacket that made him stand out from the rest.
In keeping with his hit single 'Suit & Tie', the singer also sported a black bow tie and he completed his look with a pair of shiny black shoes.
Joining him for photos throughout the night were actors Samuel L Jackson and Michael Douglas, as well as designer Tom Ford, Sir Elton and producer Pharrell Williams, who Justin has recorded with on numerous occasions.
The talented men looked like they were having a great time yesterday, as they were caught laughing and joking together.
It's probably just as well that Justin was surrounded by pals for the night, since he arrived at the award ceremony without his usual arm candy.
The 'SexyBack' star's wife Jessica Biel did not accompany him to London and instead appears to have stayed in America with the couple's dog Tina.
Well, jet setting across the globe can get pretty tiring. Especially when you do it as much as Justin does!
