Watch Justin Bieber Get Wild and Slam Shots in a Boston Bar

If Justin Bieber’s got beef with his fans, he didn’t show it as he partied hard in a couple of Boston bars like any other 22-year-old … who can afford round after round of shots.

After his Purpose concert Wednesday, Justin hit up Storyville nightclub and looked totally comfortable being the life of the party. He was up on the bar doing tequila shots, and didn’t mind people taking photos. A rep from 6one7 Productions tells us he racked up about $2,400 worth of tequila and vodka.

Cool moment in the video — the DJ bumping Justin … Timberlake, that is. Watch the video and continue reading at TMZ…
