Who will rule the red carpet at this year's Oscars and who will find themselves on the worst dressed list?
The stars have started arriving for the 83rd annual Academy Awards ceremony at the Kodak Theatre in Hollywood.
Mila Kunis, in a lavender, lacy, Elie Saab talked about how she prepared for her role in Black Swan, saying she lost weight by eating a calorie controlled diet and danced for several hours a day, every day.
Cate Blanchett also chose to wear lavender.
Many actresses seem to have taken their cue from Black Swan on the red carpet.
Hailee Steinfeld, who is nominated for Best Actress for her turn in True Grit wore a ballerina-inspired Marchesa gown, while Mandy Moore wore a Monique Lhuillier gown with an elegant updo.
Florence Welch, who will perform at the ceremony, looked ethereal in a Valentino dress which highlighted her porcelain complexion.
Co-host Anne Hathaway fell back onto her favourite colour - red.
She was one of many actresses who opted to heat up the red carpet in bold hues.
Jennifer Lawrence, who is up for a Best Actress nomination, looked stunning in a red dress by Calvin Klein Collection, opting for natural make-up and hair and minimal jewellery.
Sandra Bullock also wore a red gown by Vera Wang.
Jennifer Hudson wore a tangerine orange Versace gown, saying she didn't want to take her dress off when she first tried it on three days ago.
Amy Adams wore a navy blue sequinned L'Wren Scott dress with a high neckline and a daring split up the side of the gown.
Michelle Williams also plumped for a dress with a high neckline and capped sleeves.
AIMING FOR YOUNG AUDIENCE
Today's Oscars presentation will feature two youthful co-hosts, actors James Franco, 32, and Anne Hathaway, 28, marking the first time a man and woman have presided over the Oscars.
Hathaway is the youngest person to MC what is annually the second most-watched TV show in the United States and broadcast live in more than 200 countries worldwide.
The King's Speech and Facebook film The Social Network are widely considered front-runners to be named best movie by the Academy of Motion Picture Arts and Sciences.
Best actress and actor nominees including Nicole Kidman, Natalie Portman, Javier Bardem and Colin Firth will parade up the red carpet outside Hollywood's Kodak Theater in fashionable gowns and tuxedos ahead of the ceremony on Sunday night.
Producers say the ceremony, at which more than 20 awards will be given out in just over three hours, is meant to connect movie fans to the Hollywood of old, while also giving a nod to the future with web cams and Twitter feeds.
