Off with their heads! Alessandra Ambrosio smoulders as Alice in Wonderland's evil Queen of Hearts as she celebrates

She definitely couldn't be accused of doing things by half, as Alessandra Ambrosio looked sensational as she dressed up as the much-hated Queen from Alice in Wonderland.
The Brazilian model went red for the evening when she attended the Casamigos Halloween bash at the home of Mike Meldman in Beverley Hills on Friday.
The 32-year-old smouldered under her bright bob, as she arrived in her eye-catching black satin outfit.

Sporting a cute gold crown, the star showed off her enviable legs in knee-high socks which had hearts, clubs, spades and diamonds printed up them.
The cleavage-baring look included a corset and a very short, frilly skirt, as well as a large collar and shiny cape.
The Victoria Secret model arrived with friends who looked equally as good, including one dressed as a rabbit in a daring white leotard and matching boots.

Alessandra posted a photo on Instagram during her night out, with the caption: 'Where is Alice? #halloween'.
The normally brunette-beauty's outfit also included large puff sleeves and simple black patent heels, with the infamous, and perfectly matching, Louboutin sole.
The star wasn't the only celeb going all out at the party ahead of October 31, as Vanessa Hudgens arrived complete with fluffy halo and wings.

The 24-year-old appeared ready to take flight in her feathered white design, as she came over all angelic for the occasion.
Accessorizing with a pale, gold sequined T-shirt and fishnet tights, the actress also wore overly fluffy legwarmers and socks.
Getting into the spirit, she tweeted earlier in the day: 'Best Halloween salon movie everrrrr @ninezeroone #inlovewithsarahjessicaparker'.

Time to samba! Molly Sims channels Carmen Miranda in her glamorous gown

Fellow guest Molly Sims added even more height to her already tall frame in a Carmen Miranda inspired ensemble, complete with pineapple headdress.
The 40-year-old showed off her envious physique in a figure-hugging floor-length gown, which featured head-to-toe pink sequins.

Isla Fisher and her husband Sacha Baron Cohen must have worn the oddest outfits of the evening, with the actress sporting striped leggings, tiger mask and frilly skirt.
