We're dating: Justin Biber and Selena Gomez kiss outside Vanity Fair Oscars partyThey've been quietly dating since November but have been maintaining a low profile.
But 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.
And as they enjoyed long lingering kisses in front of the cameras outside the party, and happily showed off a photobooth shot of them puckering up, there were no mistake that they were a couple.
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.

Let's hope the Beliebers don't see: Selena and Justin pucker up for the cameras in the photoboothGomez 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.'

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.'

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.'

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.'

However, while Hailee missed out on the gong to The Fighter's Melissa Leo, she still managed to enjoy herself, switching her high heels for comfy Converse plimsolls as she arrived at the Vanity Fair party.
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.'
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.
