Following his Comedy Central roast, Justin Bieber headed to Las Vegas to continue his never-ending 21st birthday celebration at Omnia nightclub inside Caesars Palace on Saturday night, March 14. The party was attended by Justin's friends including manager Scooter Braun, stylist Ryan Good, Ashley Benson and David Arquette.

In a video recorded by a fan, Justin could be seen jumping on the table and showing off his dance moves before he sang "Happy Birthday" to himself. "Happy Birthday to me, Happy Birthday to me, Happy Birthday to me," he sang. After the events, Justin tweeted, "Tonight was one of the best nights ever. Thank you to everyone involved. Thank you."

According to PEOPLE, the "Never Say Never" singer "danced on the table, he drank vodka and he talked to basically every girl security guards would let go near him" during the bash. A source told the site that Kris Jenner, who was also at the club, popped by to greet Justin. "He looked really good," the source said of Justin, "Focused and not a mess." He reportedly left at around 4:00 A.M.

On Sunday, Justin took to Instagram to promote his friend Kevin Hart's upcoming movie "Get Hard". Wearing a black suit and white angel wings, the "Baby" hitmaker said, "Make sure this weekend you go see my boy Kevin Hart in the movie 'Get Hard'," before making a silly pose.
