PREGNANT Rosie Huntington-Whiteley led a stream of scantily-clad stars at the 2017 Oscars Vanity Fair after party last night.

Everyone from Jennifer Aniston to Emily Ratajkowski, Mariah Carey and Katy Perry showed off their incredible figures in full glamour.

Mariah Carey risked a wardrobe malfunction in a plunging green gown, defying the legs and cleavage rule completely.

The star was all smiles as she showed off her world famous curves in the thigh-split dress, and towered in black stilettos.

Supermodel Rosie showed off her growing front in a floor-length silver dress, flashing her toned leg in a daring thigh-split.

The star wore her hair tied back in an elegant do and flashed a beaming smile for photos outside.

Meanwhile Friends star Jennifer looked gorgeous as she posed with husband Justin Theroux as they arrived at the annual bash, a favourite with winners and guests alike.

The dress also had a plunging neckline almost down to 48-year-old Jennifer's navel, but she kept her make-up and accessories simple.

Her long brown hair was slick and loose down her back and she teamed her sexy frock with simple strappy black sandals and a clutch bag.

She looked composed as she made her way inside the party after getting emotional as she introduced the In Memoriam segment during last night's Oscars ceremony.

"Every one was a cherished member of our Hollywood family... as was beloved friend and actor who left us just yesterday, Bill Paxton."

She then broke off to compose herself as she choked up before continuing the introduction and said: "Let us remember their lives and their beautiful work. All were loved, and all will be missed."

Jessica Alba, who posed with husband Cash Warren on the red carpet, wore a baby blue sleeveless ruffled gown with a split up her left thigh.

Her hair was pulled back into a slick high ponytail and she matched the dress with silver platform heels and a silver clutch.

The red carpet soon started filling up as the creme de le creme of Hollywood left the Dolby Theatre on Hollywood Boulevard.

Amy Adams looked very vintage Hollywood in her plunging silver gown, her sleek red hair swept to one side in soft waves.

Kate Bosworth appeared to channel Grace Kelly as she swished into the party in a sea blue full-skirted chiffon dress, her hair pinned back in waves, and a smear of red on her lips.

She was joined by friend Diane Kruger, who also flashed her pins in a very unusual short silver dress which showed off her slender frame.

Other guests demanding the flashbulbs attention included Fifty Shade star Dakota Johnson, who looked very chic in her plunging black gown which was decorated with a long peach belt tied in a huge bow.

Poppy Delevingne looked very pretty in her plunging nude gown with silver decor and model Kate Upton, who, like Amy and Kate, went old school Hollywood in a plunging blue sequined dress which showed off her impressive curves.

Reese, like Diane, kept it short as she posed for the cameras in a black patterned dress with long sleeves which she teamed with strappy heels and simple clutch.

Demi Lovato, who arrived with Joe and Nick Jonas, stood out in her long lilac feathered dress, while Gabrielle Union left very little to the imagination in her blue and black cutaway dress that just about protected her modesty.

Isla Fisher looked chic in a strapless canary yellow satin dress as she arrived with husband Sacha Baron Cohen and Olivia Munn bucked the trend to flash the flesh as she wore a long red lace and chiffon dress with long sleeves and a high neckline.

Lily Collins also went for a plunging black frock which was slightly see-through and was hemmed with feathers, and Kate Beckinsale had a similar outfit except her sleeves were decorated with black chiffon.

There were also two baby bumps getting in on the action as Rosie Huntington-Whitely, on the arm of fiance Jason Statham, showed off hers in a slinky silver dress while singer Ciara showed off hers in a plunging red velvet dress.
