Sparkles, sequins and metallics were definitely a popular choice:

Katy Perry wears a dress by Lebanese designer ZUHAIR MURAD paired with ROCK & REPUBLIC heels and Kristen Stewart is in DOLCE & GABBANA - note the mixing of fabrics / textures (a tweed silver mini-skirt with a gold brocade top).

Lindsay Lohan took the theme to the next level with this PAMELLA ROLAND blinged out jumpsuit, with a dangerously low-cut V-neck... and I don't know what catches your eye first with Audrina Patridge's ensemble - the mirror-effect silver dress by CD Greene Couture? Or those fabulous studded GIUSEPPE ZANOTTI sandals?!

Eva Mendes shined in this STELLA MCCARTNEY off-the-shoulder dress from the Pre-Fall 2010 collection with gold open-toe heels.

Also popular, were feathers:

Jessica Biel looks like a total sweetheart in a GIAMBATTISTA VALLI dress from the Fall 2010 collection and Paris Hilton arrived in full plumage with her BLUMARINE strapless satin mini-dress.

Then Christina Aguilera took the cake, with this feather-effect VERSACE ATELIER gown complete with chains 'n' things.

The next look was lace:

Scarlett Johansson looked incredible in head-to-toe DOLCE & GABBANA and was easliy one of the best-dressed on the night. Amanda Seyfried also sported a dress with sheer lace detailing for the event.

If is wasn't lace, sequins, sparkles or plumes - these celebrities still got attention with their bold choices:

It's impossible to miss Jackson Rathbone in this MOODS OF NORWAY blazer in a brilliant blue, the rest I believe is JOHN VARVATOS. Whitney Port makes a statement in this strapless chiffon dress with yellow and nude panels intertwining.

Rockin' the red carpet in bold floral prints were...

Twilight's Anna Kendrick in a ZAC POSEN frock, whilst Nikki Reed wore a dress by MIU MIU.

The guys played it safe with jeans and an open-collared-shirt accompanied by a blazer...

Tom Crusie with Cameron Diaz (hello floral print) and Vanessa Hudgens wearing a shimmery JENNY PACKHAM dress with Zac Efron.
