Justin Bieber celebrated his 18th birthday in several big ways. He was showered with gifts on Ellen DeGeneres' TV show, receiving a car, hanging out with a superfan and chilling backstage with Sophia Grace and Rosie. His father even had his initials inked on his side!

Despite those very public presents and birthday activities, the 18-year-old also made time for a low key but luxe dinner with friends and family at a restaurant in Los Angeles, followed by an exclusive party. Word had spread before the big day that the Biebs was hoping to keep his party with friends and family on the quiet tip.

The Biebs' lady love Selena Gomez wasn't able to be at the dinner since duty called; she was in Florida filming the movie 'Spring Breakers.' It's likely she and the Biebs made time for their own special b-day fete out of the spotlight, too.

Gomez did make it to his slightly more A-list and poppin' party, however! She flew out from filming just to be with her beau on his big day. How cute are these two?! Pals at the party included Kim Kardashian, Ashley Tisdale and Kendall and Kylie Jenner.

You can check out the photos below and see that there is a big screen that featured a slideshow of pics of Bieber throughout his life.

Once again, happy birthday to Justin Bieber! He's one special kid. Wait, he's 18 now. We can't exactly refer to him as a kid anymore, since he's growing up before our very eyes.
