It's been a night of beautiful gowns and elated speeches at the 2012 Academy Awards in LA, with this year's ceremony delivering jokes, tears and even the odd yap (courtesy of Uggie, The Artist's dog).
Punters' favourite Meryl Streep walked away with the best actress gong for her impersonation of Maggie Thatcher in The Iron Lady, drawing an enormous whoop of appreciation from the star-packed audience at the Hollywood & Highland Center.
Meryl, the most nominated actress in Oscar history with 17 nods, was self-deprecating as she accepted her third Academy Award - and first since 1983 for Sophie's Choice.
"When they called my name I imagined half of America going 'Aw, no! Her! Again!'" she joked, before thanking all her friends, her voice shaking with emotion.
She saw off a headline cast of formidable contenders with the win, including Viola Davis, Michelle Williams, Rooney Mara and Glenn Close.
Earlier on in the evening, an overwhelmed Octavia Spencer fought back tears as she picked up the gong for best supporting actress for her role in The Help, the movie adaptation of Kathryn Stockett's best-selling novel.
"I'm wrapping up! I'm freaking out!" she told the crowd, after thanking her family in Alabama and a string of others.
Over in the best actor category, Jean Dujardin brought a smile to many peoples' faces with his elated acceptance speech for his lead role in silent movie The Artist.
"I love your country," he announced. "If George Valentin (his character in The Artist) could speak, he would say: Merci! Formidable!"
The Artist also saw victory in the best picture shortlist, beating off competition from eight other films, including Martin Scorsese's animated adventure flick Hugo (the most nominated film of the evening). Michel Hazanavicius won best director for the homage to Hollywood's golden era of film.
Billy Crystal returned as Oscars host for the first time in eight years, in what some critics lambasted as a play-safe performance. The veteran presenter opened the ceremony with a video sequence that showed him getting kissed by George Clooney. "You're a lucky girl. He's a very good kisser," he told the star's girlfriend Stacy Keibler. The customary jokes followed, including a dig at Christian Bale, one of the evening's presenters, for his infamous on-set rant.
A host of A-List stars comprised the rest of the evening's guest presenters, including Ben Stiller and Emma Stone, the cast of Bridesmaids, Gwyneth Paltrow and Robert Downey Jr., and Angelina Jolie. Miss Piggy and Kermit the Frog also put in an appearance.
Sacha Baron Cohen created a stir on the red carpet earlier on in the evening by dressing up as The Dictator, the star of his latest movie, and pouring ashes "from the urn of Kim Jong-Il" over radio host Ryan Seacrest.
