Catered by the fast food franchise In-N-Out Burger, the 2015 Oscar nominees, winners and performers mingled in the setting of the Wallis Annenberg Centre. After an evening of powerful speeches and nail-biting announcements, the A-listers headed to the annual Vanity Fair Oscars after party.

Jennifer Aniston and fiancé Justin Theroux danced the night away to a musical line-up curated by New York based musician D.J. Mateo that blended classic songs from the golden age of Hollywood with this year's chart-toppers.

Anna Wintour arrived with daughter Bee Shaffer, whilst Felicity Jones and Marion Cotillard switched up their earlier Oscars red carpet looks – transforming into new gowns by Saint Laurent and Giambattista Valli respectively.

The exclusive event was also attended by some of the music world's biggest names including Rita Ora, Jennifer Lopez and Beyoncé – who stunned in a beautiful white Stella McCartney dress and white fur stole. Sia arrived with husband Erik Anders in a very demure beige cape and matching pleated trousers, rocking her customary face-obscuring platinum wig and accessorised with a black hat.
