Sunday night is the 84th Academy Awards, and stars will be pulling out all the stops for their Oscars red carpet moment. The night never fails to bring us a few fashion surprises, but one thing we can guarantee is that you'll have an amazing night if you love glamorous gowns!

On Sunday, team Catwalk Queen will be having a little Oscars party of our own, livetweeting the red carpet and updating the site as soon as the photos come in so you can see the gowns for yourself.

In my role as resident Oscars expert, I always predict what I think people will wear, and while they usually pull something new and exciting out of the bag to prove me wrong, it's still fun to guess.

With dozens of beautiful women attending this year, I can't possibly predict them all, so I've picked six high profile nominees and presenters to speculate about now. Here's what I think Hollywood's finest will be wearing on Oscar night...

Jennifer Lopez (Presenter)

During the Marc Anthony years, Jennifer's style softened and her awards show dresses got a bit more romantic. She's worn Zuhair Murad, Chanel, Armani and plenty of Marchesa in recent years, and there's a big chance she might go for one of those again this time around - perhaps a sexy, low-backed number from Marchesa (middle). But something tells me Jennifer might go all out this year with something much sexier, perhaps a sparkling silver number from Atelier Versace (left) or something sheer and see-through by Gucci. I'm not discounting colour either - perhaps she'll go really bold with an acid green or orange?

Michelle Williams (Nominee)

She may have surprised at the BAFTA Awards in an H&M Conscious Collection gown, but for the Oscars I think Michelle will turn to one of her tried-and-tested designer favourites. No doubt she's been in talks with Kaiser Karl, and a custom Chanel couture number would be a good bet, perhaps based on the very blue S/S collection with its 20s feel (left). That said, we know Michelle is not afraid of colour (she famously wore buttercup yellow Vera Wang to the Oscars in 2006) but recently she's favoured simple shapes, so perhaps the chic short-sleeved pink gown from Giambattista Valli's first couture collection (middle) will appeal. If she's feeling more romantic, Valentino's beautifully wistful floral dress (right) would look beautiful on her and definitely leaves Marilyn behind.

Cameron Diaz (Presenter)

If you believe the rumours, Cameron (along with Gwyneth and Charlize) has requested a dress from Victoria Beckham for the Oscars, so it's likely we might see her in one of Victoria's super-simple sheaths; but the question is will it be a new design (like the mutistrap navy Spring / Summer halter on the left) or will Victoria go back into the archives? If the Beckham rumours turn out to be untrue (or if Cam changes her mind) then I'd love to see her in Stella McCartney - her killer athletic body is made for the sporty navy and white number with gold belt (right). Maybe she'll surprise us all and go for something far more dramatic in a bright, fun colour - Armani Prive's green layered gown (centre) would look knockout on Cameron!

Angelina Jolie (Presenter)

The Jenny Packham AW 2012 collection was made for Angelina, and after she's worn the designer's dresses twice recently, it's not out of the realms of possibility that she'll choose Packham again for the Oscars. The dream choice for me would be the dramatic red number (centre) which would really shock those expecting Angelina to wear black...though if she does go for her failsafe colour, there were plenty of dramatic options in the same collection. Elsewhere, Angie's fave Atelier Versace dished up a sharp-shouldered textured grey dress that would look Killer on Ms Jolie. As a wildcard choice, up and coming designer Prabal Gurung's pre-fall collection featured a pair of beautiful 1930s inspired gowns that would suit Angelina brilliantly. I'd love to see her in the deep green satin number (right).

Rooney Mara (Nominee)

Rooney tends to go for strong, modern looks, but is also surprisingly big fan of lace, having worn red Valentino and white Givenchy whilst promoting The Girl With The Dragon Tattoo. At the Golden Globes she opted for black cut-out Nina Ricci, but for the Oscars I predict she'll go for either a pale colour or something heavily textured. Givenchy Couture's tought brown crocodile scaled dress (left) would be a fitting choice for the girl nominated for her portrayal of Lisbeth Salander, but a high-necked, heavily embellished golden gown from Valentino Couture (middle) might be more likely. If she does go dark, here's hoping it's with some serious drama - a shattered, distressed lacy gown from Alexander McQueen (right) would look amazing with Rooney's short hair and sharp cheekbones!

Emma Stone - Presenter

Emma has a flawless red carpet record, with a knack for choosing bold colours and pieces with interesting detail, so I'm really excited to see what she wears to the Oscars. Predicting is pretty difficult - she's worn everything from McQueen to Calvin Klein, Tom Ford to Luca Luca, but she does have a bit of a soft spot for Lanvin. What I'd really love would be for Emma to go all out with a British designer - Giles (centre) has a sense of humour that I think would appeal and his dresses are definitely dramatic. However, Emma isn't a big gown girl, so perhaps Vionnet's slouchy bias-cut yellow dress with butterflies is more likely - the colour would look amazing with her red hair. Elsewhere, Elie Saab is always a safe bet for Oscar glamour, and his Spring / Summer collection was full of gorgeous pastel pieces that would look beautiful on Emma.

As for me, well, in my head I'll be wearing this glorious Zac Posen creation...

But you'll have to wait until Sunday to see what I'm actually wearing!
