Love's young dream: Selena Gomez and Justin Bieber made their red carpet debut together at the Vanity Fair Oscar party in Los Angeles last night

They've been quietly dating since November but have been maintaining a low profile ever since.

But last night, teen sensations Justin Bieber and Selena Gomez finally confirmed their relationship by making their first official red carpet debut at the Vanity Fair Oscar party in Los Angeles.

With their arms wrapped around each other, the young pair stared lovingly into each others' eyes as they posed for photographers on the red carpet outside the Sunset Tower Hotel.

The couple had even colour coordinated their outfits for the occasion, with 16-year-old Bieber donning a red pocket square in his black Dolce & Gabbana suit to complement 18-year-old Gomez's floor-length red gown, also by D&G.

Wizards of Waverley Place star Gomez accessorised her Grecian-inspired gown with Brian Atwood heels, Judith Leiber bag and Lorraine Schwartz jewels.

Gomez and Bieber were first romantically linked last year, after a series of meetings including Gomez visiting Bieber on his tour bus.

However, the Disney sensations declined to comment on their pairing for months, instead answering coyly about the status of their relationship.

Recently, a bold fan quizzed Bieber during an MTV question and answer session if he was dating the stunning singer and actress, to which he replied: 'I think anyone would be lucky to date her. She’s a great person.'

He later added: 'I like girls with nice, pretty eyes and a nice smile. I like girls that are funny because I like to laugh and joke around.'

Gomez has maintained an equally coy attitude about Bieber, saying previously that she considers the Never Say Never star family.

Recalling the first time the pair met, Gomez explained: 'When he first started to come over from Canada his manager contacted me and he just said that he would like to meet me and he was just such a good kid.

'I feel like a big sister now, because I want to protect him.'

But when she was asked if she was suffering from 'Bieber Fever' at the Grammy Awards last month, Gomez replied to Access Hollywood: 'I love him. He’s been in my life a very long time. He’s my friend.'

Gomez added she wasn't worried about the attention she was getting for her relationship with Bieber, despite Kim Kardashian receiving death threats from hundreds of fans when she and the singer joked about a mutual crush.

Gomez laughed: 'I think it’s awesome people are interested – I don’t understand why.'
Bieber and Gomez looked delighted to be mixing with Hollywood royalty at the Vanity Fair party as they made their way into the exclusive event.

Earlier in the evening, Bieber had backed True Grit star Hailee Steinfeld to take home the Best Supporting Actress Oscar.

He tweeted: 'Good luck to my friend Hailee Steinfeld tonight on the #oscars . young people going for theirs! also want Christian Bale to win. #TheFighter.'

But it seems the grandeur of the party might have reminded Bieber of how lucky he has been, as he later added on Twitter: 'i'm never gonna change...i will always remember...i will always be that kid from stratford...I will always be grateful.'

Grown-up glamour: Emma Stone opted for a Chanel dress, while True Blood star Anna Paquin went for red

The cute couple weren't the only young celebrities gracing the red carpet at the star-studded event.

Country star Taylor Swift caused a stir in a tiny jewelled gold Zuhair Murad dress, while actresses Emma Stone and True Blood star Anna Paquin went for very different looks for the party.

Stone opted for an oriental-inspired Chanel Haute Couture dress with purple satin heels, while newlywed Paquin looked stunning in a ruffled red Monique Lhuillier dress and Brian Atwood black shoes.
