Need any Help Actress Jessica Chastain goes braless in plunging McQueen at Vanity Fair party
With a host of award nominations and her critically-acclaimed performances in The Help, Take Shelter and The Tree Of Life, Jessica Chastain is one of the Hollywood's rising stars.
But the redhead actress showed she's just not talented in the acting department as she showed off her stunning figure in a daring dress last night.
The film star, 30, wore a plunging Alexander McQueen Spring/Summer 2012 creation with a high collar and peplum detailing and a pair of Jimmy Choo sandals.

Chastain was one of a host of stars attending the Vanity Fair and Juicy Couture event to celebrate the 20th anniversary of the magazine's 'Vanities' section at the Siren Studios in Hollywood.
The event is one of many in the run-up to this weekend's Academy Awards, which sees Chastain competing for Best Supporting Actress in The Help.
Chastain is up against her co-star Octavia Spencer – who played her character Celia Foote's maid Minny Jackson – in the category.

Spencer has already pipped Chastain to the title at several awards show so far, including this month's Baftas.
Laid-back Chastain admitted she doesn't expect to win and is pleased to be nominated after a whirlwind year for her career.
She said last week: 'It’s not nerve-wracking in the way that I have a feeling like: “Urgh, I am gonna win!” I think what it is, is that for the rest of my life it will say “Oscar nominated Jessica Chastain… Golden Globe nominated, Bafta nominated…” It’s crazy.

'Right now at this moment in my life it’s not incredibly important to win. It’s more important to be in that room and to get to meet my idols.
'I hope to have a very long career so I don’t want to look at it like this is my only chance.'
Last night's Vanties bash was hosted by actress Shailene Woodley, with proceeds from the magazine's Campaign Hollywood week going to her non-profit organisation All It Takes.
Other stars in attendance included Amy Adams, Hayden Panettiere, Emmy Rossum, Olivia Munn, Anna Kendrick, Marcia Gay Harden and Molly Sims.
