Justin Bieber made the scene at Kendall Jenner’s 20th birthday party in Los Angeles Monday night (Nov. 1), wearing a green jacket with the word “Gangsters” on back. Is he posing again? He was also spotted with another bad habit.

The pop star’s green “Gangsters” wind breaker sparked questions. “Are you a gangster?” one photog shouted.

“I’m the farthest thing from a gangster,” Bieber shouted back, laughing, as he walked into The Nice Guy restaurant where Kendall was waiting.

Later, however, Justin was also spotted outside lighting up a cigarette. It’s unknown how long he’s been smoking. He’s rarely, if ever, been seen in public with a butt. But he’s known to smoke marijuana.

Who knows? He may have picked up the habit from Selena Gomez, who started smoking after filming her 2013 movie “Spring Breakers.” She’s alarmed friends since for chain smoking.

More likely, Biebs just picked up the habit, because, you know, it’s a cool Gangsta’ thing to do.

Ironically, Justin posted a photo on Instagram a year ago in March with a cigarette in his mouth, He was emulating a famous photo of actor James Dean.

His fans were so upset, his management immediately let it be known that Justin didn’t smoke. But times obviously change.

The 21-year-old singer has been struggling with his image ever since his 18-month spree of loutish behavior and string of arrests.

Despite turning over a new leaf, however, Bieber threw a highly unprofessional tantrum last week during a show being taped for television in Norway.

He later apologized for the incident and appeared in good spirits Monday night, according to X17online paps who were there.
