Much has been made about Justin Bieber‘s 18th birthday, which was March 1. He received a plethora of amazing gifts — an electric car for himself, while his dad went the sentimental route and etched The Biebs’ initials on his body in tattoo form.

But perhaps the best gift of all? His girlfriend Selena Gomez serenaded him at his birthday party, which was held at the Regent Beverly Wilshire Hotel in Los Angeles. How romantic. What a precious pair these two make!

Wearing a black dress and heels, Gomez, who flew in from Florida, where she is filming ‘Spring Breakers,’ sang along to ‘Call Me Maybe,’ which all self-respecting and informed Beliebers know is Carly Rae Jepsen‘s single. She is signed to The Biebs’ label, so the song is clearly a fave among his crew. They all support each other, even during party time.

Jepsen sang. Gomez sang. The Biebs danced. You can see him shuffle across the screen and run his palms through that famous head of hair of his. Even former ‘High School Musical’ star Ashley Tisdale was in the house and she rocked out, too. This was quiet a fun par-tay, judging from all the news, photos and videos that are popping up online in the ensuing days.

Oh to be young, famous, beautiful and in love.
