Justin Bieber buys round of shots for everyone in bar in Los Angeles

Bieber will kick off a 58-date tour promoting his new album in Seattle on March 9 and it will end in New York City's Madison Square Garden on July 18th.

Justin Bieber made a surprise guest appearance with The Chainsmokers during their concert at the nearby Shrine Auditorium.

According to Daily Mail, before the concert the 21-year-old Canadian singer popped into a college bar in Los Angeles on Friday and bought a round of shots for everyone.

Bieber stopped at the 901 Bar and Grill near the campus of the University Of Southern California. 

A snap shared on Twitter showed the singer amid a throng of patrons at the longtime USC bar established in 1947.

'When @justinbieber buys you shots at the 9-0 #FightOn,' another student posted on Twitter.
