The 22-year-old pop megastar descended on Leicester Square, London, with a variety of celebrity pals on Monday night (28.11.16) as he attended the glitzy premiere of the biopic movie about Olympian Usain Bolt, as well as the party at Tape nightclub which took place afterwards.

Alongside Justin and the One Direction singer, stars such as fellow singers Fleur East and Geri Horner, comedian Jimmy Carr, and British Olympian Mo Farah were also in attendance for the big event.

Posting on Snapchat during the event, the 'Sorry' hitmaker appeared in a video with the 30-year-old sprinter where the pair appeared to make a variety of funny faces to the camera.

Usain also posted a video to his own Snapchat account, where the pair appear to be having a good time as they grin and laugh at the camera.

Meanwhile, Liam took to Instagram before the premiere to post a picture of the movie poster, detailing how he was "looking forward" to watching the feature.

'I Am Bolt' focuses on the record breaking career of the nine-time Olympic gold medallist - who is regarded as the fastest human ever timed - and follows him during his gruelling training as well as giving fans an insight to his home life.

Both Justin and Liam were pictured leaving Tape nightclub in the early hours of the morning, and looked worse for wear as they stumbled into their respective cars after a night of partying.
