Justin Bieber showers kisses on Selena Gomez

A whole host of people were out in force last night to help Justin Bieber celebrate his 18th birthday.

But the singer only had eyes for one guest at his party, his glamorous girlfriend Selena Gomez.

The actress and singer was in Florida working on her upcoming movie Spring Breakers but flew in especially for the evening.

It's good to be 18 when you're Justin Bieber.

First, on The Ellen DeGeneres Show, the teen heartthrob was surprised with a massive gift from Usher and his manager, Scooter Braun: a Fisker Karma, an electric luxury car worth over $100,000.

"I always yell at you, don't get anything flashy, we're not about that. Be humble, be humble," said Braun. "I kind of broke my own rule."

The same day, Selena Gomez, 19, took to Twitter to fete her boyfriend. "Happy birthday to my best friend in the whole world!!!!" she tweeted.

Then, Daily Mail reports that on Friday Gomez flew in from the Florida set of her new film, 'Spring Breakers', to attend Justin's birthday party in Los Angeles. Justin, dapper in a black and white dogtooth jacket, sported an Elvis inspired 'do.

And in a series of pictures posted to Twitter, the happy birthday boy can be seen planting a kiss on Selena's cheek (she wore a festive red strapless dress).

"NO MATTER WHAT WE PARTY TONIGHT," the Biebz tweeted pre-festivities. Looks like it was quite a bash. Later, he signed off with: "#greatnight."

Justin had held a dinner party to celebrate turning 18 on the evening of his birthday on March 1, but Selena was unable to attend due to work commitments.
