Walkies: Amanda Seyfried arrives at Kate Hudson's A-list Halloween party dressed as a dog

Tricks, treats and an embarrassing wardrobe malfunction marked Halloween celebrations in Hollywood last night.

Kate Hudson's annual party proved the place to be as a host of A-list stars descended on the 31-year-old's home in Pacific Palisades.

While many famous faces turned up, some where rather hard to recognise thanks to clever costuming.

Mamma Mia star Amanda Seyfried sensibly stayed cosy inside a huge furry dog suit, while Gwen Stefani hid her face behind a black patent mask as Catwoman - but her signature red lipstick gave her away.

Leonardo DiCaprio did a good job of concealing his identity in a baboon mask, which he oddly chose to accessorise with a man purse slung over his shoulder.

Celebrity stylist Rachel Zoe shaved off the years with some pig tails and a head band as Pocahontas, while Nicole Richie made less of an effort, simply throwing on a fur coat and a diamante hair slide for some Hollywood glamour.

Also apparently raiding their normal wardrobe was actor David Spade, who wore a tracksuit and carried a whistle and clipboard as Glee's sports coach, Sue Sylvester.

Kate's step-father looked sombre as a decorated military man, including beret and badges, while veteran rocker Steven Tyler played the devil in a pair of red horns.

Also enjoying Kate's hospitality was 90210 star Shenae Grimes who appeared to have gone prematurely grey.

The party in Pacific Palisades may have been the frontrunner last night, but not to be outdone, Paris Hilton had her own bash, dressing up as a sexy Indian warrior princess,

However, the outfit proved a little to skimpy, with her top slipping down to reveal rather more than she intended.

Her rather more demure sister Nicky was cute as a button in a Minnie Mouse get-up.
Paris and Nicky's parents, Rick and Kathy Hilton mugged it up as a pair off police officers, with Kathy in a pair of sexy patent leather knee boots and gun holster belt.

Actress Kim Porter celebrated last year's biggest movie, Avatar, in her skin-tight electric-clue body stocking and blue face paint, receiving admiring glances from fellow guests.

Meanwhile earlier in the day, the stars were dressing up on behalf of children affected by AIDS at an event in Santa Monica.

Tori Spelling sported a peacock outfit with black tutu and feathered bodice, teamed with turquoise tights, feathery shoes and a black wig.

Drama: Lady Gaga (L) rocks a Cruella de Vil outfit complete with gun in Belfast, while AnnaLynne McCord (R) is a fairy princess in Vegas

Lady Gaga unsurprisingly chose an outrageous look, sporting a dalmatian-print coat left open to reveal sexy black underwear with a trail of fake blood splashed over her neck and chest.

She completed the look with black and white hair, huge black sunglasses and a pistol in hand.

US TV favourite, Brooke Burke touted her stunning figure in a leather catsuit with matching mask and ears, as Catwoman.

At the same event acting veteran Jamie Lee Curtis showed off her fantastic legs in a cheerleader outfit complete with megaphone.

Also recalling her school days was Jenni 'JWoww' Farley from The Jersey Shore, who went all-out in a mini kilt, knee socks and white blonde knotted under a sexy red satin bra as she hosted a club night in Atlanta.

Jersey gal pal Nicole 'Snooki' Polizzi, dressed up as her favourite snack - a pickle for a party in Vegas.

The Jersey Shore diminutive star wore a green sequinned mini-dress, green cape, green shoes and a sparkly tiara while holding a royal sceptre with a giant pickle on top.

And tonight, Kim Kardashian tweeted a photograph of herself wearing a selection of different Halloween costumes as she tried to decide which one to choose.

Both the sexy pirate get up and the clingy leopard outfit revealed her curves, with Kim writing under the leopard photograph: 'This leopard was a little too sexy for the kitties! LOL.'

Over in New York tonight, Hugh Jackman and wife Deborra-Lee Furness were getting in the Halloween spirit by taking their children Oscar, ten, and five-year-old Ava trick-or-treating.

Jackman was dressed in the style of a Victorian gentleman, complete with top hat and tails, while Furness looked more casual in black and white.

Their children seemed to be having fun decked out as a cowgirl and a Viking.

And Liv Tyler got into superhero mode, dressing up as Catwoman with her five-year-old son Milo, who was dressed in a red outfit with black feathers.

The pair were seen celebrating the occasion outside their town house in New York's West Village.

This was a weekend packed with Halloween madness in Hollywood, with surely more to come.
