The Biebs officially turned 18 Thursday — Surprised with a party at the Regent Beverly Wilshire Hotel over the weekend hosted by his manager Scooter Braun, his mom Patti Mallette and publicist Melissa Victor.

Justin Bieber, who goes by the nic-name Biebs spent the night with all his closest A-list buddies including girlfriend Selena Gomez, who flew in from filming Spring Breakers in Florida, Kim Kardashian, Kylie and Kendall Jenner along a few others.

“Everyone danced all night,” a partygoer told Us Weekly of the fete, also attended by Ashley Tisdale and Cody Simpson.

Dressed to the nines in a black and white suit, of course; the now barely legal man of the hour mingled with his close family and friends who flew in from Canada for the surprise party, but Bieber stuck by Selena’s side for most of the night.

“It’s clear she was the best part of the night for him. He is still so in love with her, he was all over Selena the whole time, walking her around by the hand. He kept kissing her,” a source close to the pop star tells Us about Bieber party PDA with Selena.

To top it all off, Bieber also received a one-of-a-kind Fisker Karma eco-friendly sports car as a gift from his manager Scooter Braun, which was given to him on the Ellen DeGeneres TV show with a reported price tag of $102,000.

“It’s all electirc?” inquired The Biebs as he looked shocked receiving the car.
