Is he falling back into his old habits? After posting a video of him and his on-and-off girlfriend rehearsing an extremely racy dance routine on Instagram not too long ago, Justin Bieber went partying in Montreal without Selena Gomez, and then reportedly went back to his hotel with three women on Saturday night.

The 20-year-old singer was spotted arriving at Buonanotte nightclub on St. Laurent Street. He was sporting a pair of sunglasses and a red baseball cap along with his black outfit to maintain a low profile during his night out. The pop star surrounded himself with his entourage of friends, as well.

According to the eyewitnesses, the crew partied for an hour and a half, and Bieber left at 3 a.m. after inviting three girls to join him in his hotel room for a private after party.

Perhaps the "Bad Day" singer was trying to keep his mind off from his latest drama with his lover. It was revealed on Saturday that Gomez reportedly purchased a new house in Los Angeles at a cost of almost $3 million. It was also claimed that the 21-year-old was against checking out any vacant mansions that were close to Bieber's Calabasas home.

In addition, the "Come & Get It" singer's deposition is set for next week regarding Justin Bieber's alleged assault against paparazzi photographer, Jeffrey Binion. "I will be serving Selena Gomez next week," said Mark DiCowden, Binion's attorney. "She witnessed Justin Bieber attack a photographer back in 2012."
