Awkward!
Longtime rivals Kate Moss and Sienna Miller ran into each other over the weekend — and to say things got tense would be an understatement.
The two ended up crossing paths behind the main stage at the Glastonbury music festival. An onlooker said of the incident:
"They refused to talk to one another, despite having practically the same group of friends who were all there. It was really strained - you could cut the atmosphere with a knife.
Kate seemed to be doing her best not to glance at Sienna and tried to act all cool. Both looked embarrassed that they had bumped into each other at all."
Unfortunately that's all that happened — no cat fights, no hair pulling, no nothing!
For the rest of the weekend, Sienna made a conscious effort to avoid seeing Cokate again by bailing on a star-studded PlayStation party.
Ha!
Who knew little Cokate could be so intimidating???

On Wednesday night Kate Moss and Kelly Osbourne spent a night out on the town with friends in London.
Cokate, Kelly and Sienna Miller's arch-enemy Sadie Frost all gathered for drinks at a local pub, but once they got bored with that the debauchery continued at Moss' home.
The group gathered in the supermodel's back garden where they drank and sang Motown songs until the wee hours of the morning.
Must have been a good time because Kelly was spotted leaving Cokate's at around 2am.
Cheers ladies!

As we mentioned earlier this month, Sienna Miller is the new face for jewelry line Piaget.
Miller is featured in their campaign for the Possession collection.
And now, check out the special behind-the-scenes footage of Miller on set, and commentary from her and those involved.
She might be known as Sluttyienna, but she's definitely looking hawt in the new ad.
Work it, 'bb!

Jewelry line Piaget has shelled out the big bucks it seems to snag Sienna Miller as the new face of their line.
Miller will be featured in Piaget's new online campaign for the 20th anniversary of their Possession collection.
Not only will Sienna appear in photos, she'll also be featured on their website and Facebook account.
Nice to see she's still getting work.

There's the girl we know and love!
Sienna Miller graced the Costume Institute Gala with her presence wearing a very low cut frock by Emilio Pucci.
Between the mullet train, the plumage and the tittay show this dress is just too much for the toothy gal.
Remember, less is more!
