The pint-sized actress, who was seen earlier in the day alongside co-star Robert Pattinson, opted to shimmer in this slinky silver number instead of the gold gown she wore to last week's BAFTAs.

And here are some more gowns for you to lust after - brought to you via last week's BAFTA.
- Meryl Streep<p> The queen of the red carpet commanded everyone's attention in black Vivienne Westwood (we love her regal-looking hairstyle too).</p>

- Michelle Williams<p> Williams shocked us all by shunning the designer gowns for H&M (yes, you read that correctly).</p>

- Gillian Anderson<p> Anderson looked stunning in this strapless gown by Sybil Connolly.</p>

- Elizabeth McGovern<p> Wow. Elizabeth McGovern has come a long way from the Abbey. She looked stunning in this strapless black number by Azagury.</p>

- Miss Piggy<p> So what did this year's red carpet host choose to wear? A Louis Vuitton dress, especially designed by Marc Jacobs, of course.</p>

- Fearne Cotton<p> We loved seeing Fearne present the red carpet TV show, but we love her rose Moschino dress even more.</p>

- Brad Pitt<p> Finally! Pitt ditched the rugged, bearded look for a more polished style in this suit by Gucci. Even if he has had his hair straightened, we think the groomed approach is a keeper.</p>

- Emilia Fox<p> Fox worked the metallic trend in this gorgeous, golden gown by Louisa Beccaria.</p>

- Tilda Swinton<p> Tilda's best look of awards season so far? Her all-white Celine ensemble paired with that AMAZING quiff got our vote for one of the best dressed ladies of the night.</p>

- Colin Firth & his wife Olivia<p> Colin Firth looked as handsome as always in Armani, but his wife Livia most definitely upstaged him in the suit stakes this year in this Paul Smith design.</p>

- Jessica Chastain<p> MyDaily's favourite star of the moment didn't disappoint in this Oscar de la Renta design.</p>

- Christina Hendricks<p> Hendricks didn't let us down in this cleavage-enhancing design by Vivienne Westwood, but the dishevelled half-up, half-down hair do? Not so sure.</p>

- Hayley Atwell<p> Got to give Atwell some points for working colour-blocking on the red carpet.</p>

- Cuba Gooding Jr<p> Gooding Jr took suave too a new red carpet level, thanks to the addition of that white scarf over the aubergine velvet blazer.</p>

- Bonnie Wright<p> We love, love, love Bonnie Wright's vintage polka dots paired with Prada accessories.</p>

- Daniel Radcliffe<p> Harry Potter got suited and booted for his red carpet moment.</p>

- Penelope Cruz<p> Penelope Cruz went for a structured Armani gown. Hot or not? We can't decide.</p>

- Edith Bowman<p> Vintage Dior or not, what on earth made Edith wear this boho-bridal dress?</p>

- George Clooney<p> George dressed for the London weather by layering up in a black coat but let's be honest, he was still the smoothest man on the red carpet.</p>

- Christina Ricci<p> Chic hair? Tick. Perfect pout? Tick. Gorgeous gown? Most definitely. Birthday girl Ricci looked amazing in Givenchy.</p>

- Jonah Hill<p> Jonah, you would look oh so smart if you learnt how to do your suit buttons up...</p>

- Holliday Grainger<p> Grainger's ethereal, golden Valentino gown was brought alive by her cherry-red lips. She definitely gets MyDaily's seal of approval.</p>

- Jessica Brown Findlay<p> The <em>Downton Abbey</em> star kept things simple in this dramatic design by Alessandra Rich.</p>

- Laura Bailey<p> Bailey looked a little too mismatched to us. She mixed a floaty, Chanel dress with tights and red pumps.</p>

- Melissa George<p> Melissa George went for a show-stopping, sparkling gown by none other than Victoria Beckham.</p>

- Michael Fassbender<p> Man of the moment Michael Fassbender worked the three piece suit.</p>

- Naomie Harris<p> Bond girl Harris braved the freezing weather in this lemon, Pucci design.</p>

- Olivia Williams<p> Williams dazzled in all-over sequins and matching accessories.</p>

- Tom Jones<p> Hello, fake tanned face. Tom Jones took glowing skin to a new extreme on the red carpet this year (but we do give him some kudos for his Tom Ford suit).</p>

- Viola Davis<p> Another name check for Valentino - Davis looked stunning in this pastel gown.</p>

- Kristen Wiig<p> <em>Bridesmaids</em> star Wiig did no frills red carpet style in this stunning gown by Ferretti.</p>

- Claudia Winkleman<p> It was a cleavage-flashing vintage Ossie Clark number for Claudia tonight.</p>

- Eddie Redmayne<p> Eddie left the ladies swooning in this velvet Burberry suit.</p>

- Gary Oldman and his wife Alexandra Edenborough<p> Oldman kept things simple in a straight-up tux while his wife Alexandra looked gorgeous in monochrome.</p>

- James Corden and Julia Carey<p> Corden's fiance Carey was pretty in pastel print while he avoided the black tie look by opting for a blue version.</p>

- Joanne Froggatt<p> Froggatt looked super sophisticated in the second Victoria Beckham gown of the night.</p>

- Douglas Booth<p> The Burberry model and actor looked oh so dapper in his super sharp suit from Hackett.</p>

- Jean Dujardin<p> It was no surprise that star of <em>The Artist </em>was one of the most popular men of the night.</p>

- Dawn Porter and Chris O'Dowd<p> The <em>Bridesmaids</em> actor was joined by his partner Dawn Porter, who looked gorgeous in royal blue.</p>

- Shailene Woodley<p> Woodley's pastel pink gown was complete with our new favourite hairstyle on the red carpet - the top knot.</p>

- Berenice Marlohe<p> Berenice Marlohe looked drop-dead gorgeous in this white column dress. Bond-girl worthy? We think so.</p>

- Helena Bonham-Carter<p> Helena Bonham-Carter stuck to her usual red carpet rules, this time in a blue dress by Giles Deacon.</p>

- Octavia Spencer<p> <font size="2"><span style="font-size:10pt;">Spencer paid tribute to <a href="http://www.mydaily.co.uk/2012/02/12/octavia-spencer-sharon-stone-bafta/" target="_blank">Sharon Stone</a> in a white shirt with a ruffled skirt by Tadashi Shoji</span></font>.</p>
