Kate Moss. Sienna Miller. Same room. Same Time. And..........smiling?!

Ok, so maybe they're not the enemies the press paint them out to be? Wouldn't be the first time the media "created" a rivalry to sell stories, but I always kinda believed this one! Guess I was wrong.

Both style "icons" were at the Make Today Count Auction at Marylebone High Street's Cancer Research UK Shop in London today. I guess they're mature enough to put their problems aside for charity - good for them!

Sienna has long been accused of stealing Kate's style. I don't believe that but they certainly have very similar taste in fashion. But whose style is better?

Actress Sienna wore flat black boots, black tights and a casual black shirt dress, brightened up with a blue scarf. I hate the hat though.

Super model Kate also wore black boots (but with heels) and black tights, but with casual grey turn-up shorts, a cool logo-tee and sophisticated black jacket. Not to mention her rock chick haircut and black shades.

Whose style do you prefer? In this case, I have to go with Kate. He look is more original and although I'm not her biggest fan, I can't deny she exudes a natural "coolness". Plus with her modelling experience, she's posing the hell out of that outfit!

I can't quite make me mind up on Sienna Miller's sense of style. Sometimes she wears something I really love, and then other times she just looks kinda.........well, dirty! And messy and like she might be trying to hard to be, quirky.

She's been taking her style global this past week! Sienna was seen at LAX airport in Los Angeles on Monday with boyfriend Rhys Ifans, spicing up a simple jeans, boots and cardigan combo with a chic cream mac and funky turquoise shades.

She was then spotted in London the following day in super-skinny black jeans, cowboy boots and layered tops. She had on a striped vest, a grey waistcoat, a knited cardigan and a chic black cardi with cropped sleeves and a ribbon tied neck. The black cardi is great but all the other layers subtract from it. And I hate trilbys!

Are you a fan of Sienna's style or not??

It's not just the world of music celebrating tonight! As well as the Grammy's, the BAFTAs (British Academy Film and Television Awards) are being held tonight too, in London.

Some of the most gorgeous gowns on the red carpet were in classic black.

Jessica Biel wore a classic strapless black Dior gown with a glamorous train, British actress Natascha McElhone looked great in a frilly strapless black gown, Sienna Miller looked grown-up and not at all her usual hippy self in a black Christian Dior Spring 2008 gown with plunging neckline and an open back, and my favourite was Thandie Newton who looked sexy in a silky black Alexander McQueen Spring 2008 gown with a sheer sleeve and a pink waist belt.

L-R: Keira Knightley, Rosamund Pike, Kate Hudson and Marion Cotillard

I also loved Keira Knightley's strapless silver tiered Valentino Spring 2008 Couture gown and Kate Hudson's dramatic metallic gold gown. She looked so much like Goldie Hawn tonight too!

And opting for shorter dresses were Rosamund Pike in a blue RM by Roland Mouret dress which I thought looked gorgeous but understated, and Marion Cotillard who wore a glamorous and sparkly silver Chanel Fall 2007 Couture dress with a matching white cape. She's everywhere these days!

Now we just have to wait for the Grammy's!

Sienna Miller really is clinging on to her Welsh actor boyfriend, Rhys Ifans. Sienna is simply famous for the men she's been with (Jude Law, Daniel Craig, P. Diddy) whereas Rhys is a very talented man.

She doesn't deserve him! Or maybe I'm being protective because he's Welsh?! Lol.

Sienna did look quite cool though in a little cream cami, skinny jeans and a stylish yellow and blue check jacket.

She could have worn clean boots though! Her Uggs are covered in paint! Maybe they've been decorating?? I hope they're not moving in together!

Fergie Ferg and her golden blonde locks were at the Fergie for Kipling Handbag Launch yesterday in a beautiful black chiffon mini dress and some seriosuly funky black and white shoes. Her hair looked really beautiful curled like that don't you think?

Christina Aguilera was glowing in a purple maxi dress on Monday in Santa Monica, which she teamed with a grey cardigan and a long gold necklace. The neckline on the dress is really hot and I love how she's matched her eye make-up to the colour (which looks great with her platinum blonde hair!).

The formerly brunette Hilary Duff is now back to her blonde roots and looking great. She was out to dinner last week in NYC with her boyfriend Mike Comrie wearing a gorgeous orange and gold dress, black leggins and cute black platforms. This outfit looks young, fun and stylish and Hilary's the perfect celeb to pull it off!

Our last stylish blonde celeb is the stunning Petra Nemcova who was at the Imitation of Christ Launch Party on Tuesday sporting a haaaaaaaaaawt leopard print dress with plunging neckline and assymetric hemline. She let the dress take the lime light with simple black court shoes and a black clutch and wore her hair half up-half down and straight.

LBBD's (Little Black Bandeau Dresses) are everywhere at the moment and they look great!

Haylie Duff was wearing a short slinky one with a tied front at Teddy's nightclub on Tuesday with sister Hilary (who also looked fab in her leggins and patterend top might I add!). She kept things simple and sexy with gold hoops and a black clutch.

Sienna Miller wore a pencil shaped one with front slit and lace bodice to a screening of Interview yesterday and looked very grown-up and sexy. She wore her black peep toes that I love again and accessorised with a patent belt around the waist and a red clutch. Her hair was simple and loose and her make-up simple and golden!

Another Brit wearing a LBBD yesterday was Lily Allen who wore hers to the Make Space Youth Review Photocall. Hers was a below the knee, prom style one which fitted great and looked very sophisticated. She kept her hair swept off her shoulders and accessories very simple with just some small hoop earrings, a white clutch and black platforms.

Who wore this look best??

Sienna Miller showed up in style to the Pepe Jeans Fashion Show in Spain on Wednesday.

Though the event was for Pepe Jeans, Sienna chose an off the shoulder, LBD and teamed it with some killer black high heels (which I love!!).
