The 'Never Say Never' hitmaker turned on his football talent at the Catalan club's training ground on Monday (21.11.16) as he had a kick about with the Spanish giants' Brazilian players Neymar and Rafinha.
He tweeted afterwards: "Great day"
Justin's skills certainly seemed to impress Brazil international Neymar, who took to Twitter to share a picture of the 22-year-old star trying to take the ball past him.
He wrote: "Impossible to dribble this defender...@justinbieber"
Rafinha also appeared to enjoy the club's special guest, as he took to Twitter to share a picture with the 'Company' hitmaker.
He wrote: "Great visit today! Nice to see you @justinbieber (sic)"
The pop star also retweeted a message from the official Barcelona account which posted a video of his "mad skills" in action, including him burying a shot into the bottom corner of the goal.
It read: "Veratile @justinbieber shows off mad #SkillsFCB with @Rafinha & @NeymarJr both on attack and in goal! (sic)"
Justin took part in the training session ahead of his show in the Spanish city's Palau Sant Jordi sporting arena on Tuesday night (22.11.16), part of his 138-date 'Purpose World Tour'.
He will head to Madrid on Wednesday (23.11.16), where he will perform at the Barclaycard Center Madrid.
It's not the first time Justin has rubbed shoulders with Barca greats.
In 2011, he also paid a visit to the club and enjoyed a chat with Lionel Messi and Andres Iniesta.
