The 22-year-old singer was at Residuals Tavern in Studio City last week when he noticed some customers were crying and asked the barman what was going on.

According to TMZ, the bartender explained that a regular at the bar had died earlier in the day after falling from his fire escape and Justin was so moved by the story that he paid the tab for the grieving group, which came to a few hundred dollars.

Meanwhile, Justin is currently maintaining a low profile after a bitter online feud with his former girlfriend Selena Gomez.

The 'Good For You' hitmaker publicly scolded Justin when he threatened to make his Instagram page private after fans lashed out over pictures he posted with his reported new girlfriend Sofia Richie, 17, but an irate Justin hit back and they ended up in a public war of words.

Both Selena, 24, and Justin each accused the other of cheating during their on/off romance and Justin also accused Selena of using him for fame.

And after threatening to make his Instagram account private, Justin has since deleted it.

The singer's fans - known as Beliebers - were left devastated after the star axed his social media account, which had 77.8 million followers.

When fans try to access his Instagram, a message now pops up reading: "Sorry, this page isn't available.

"The link you followed may be broken, or the page may have been removed. Go back to Instagram."
