Justin Bieber and Selena Gomez stepped out to the Oscars parties as a couple.
Teen singer Justin, who turns 17 this week, and Disney star Selena have been spotted out together before.
And they chose the night of the Oscars to step out as a fully fledged couple, as they took to the red carpet hand in hand - Selena wearing a scarlet dress and lipstick, and Justin donning a matching red handkerchief in his jacket pocket.
At Vanity Fair's exclusive aftershow party, the couple were spotted snuggling together in a patio booth, and Justin's mobile now has a photo of them together as its wallpaper.
Taylor Swift and her rumoured ex-boyfriend Jake Gyllenhaal were also spotted chatting at the party, although country singer Taylor was seen leaving the party alone.
By the time Black Swan actress Natalie Portman arrived with her best actress Oscar statuette in one hand, and her fiance Benjamin Millepied gripping the other, the party was in full swing. Accepting congratulations left and right, a tired but happy looking Natalie, pregnant with her first child, left after only 20 minutes.
Rapper 50 Cent wove his way through the party, as did half the cast of music-filled TV show Glee. Comedians Larry David and Sacha Baron Cohen joked together while Kevin Spacey laughed with Jimmy Kimmel. Charlize Theron joyfully hugged best supporting actor nominee Jeremy Renner.
Other celebrity attendees included Jennifer Hudson, Hugh Jackman, Donald Trump, Michelle Williams, Amy Adams and Gwyneth Paltrow, who waved to screaming fans outside and shouted "I love you too!" as she left in her limo.
