If you looked at any of the pictures from the Cannes Film Festival this year, chances are you'll have joined in the OMG SIENNA MILLER hysteria. 'Could I pull off a lob?' 'Are her Prada black sandals sold out yet?' 'Can I BE Sienna Miller?!' Another common Cannes side-effect is a Rooney Mara obsession - take 2.
We first fell for Rooney Mara's clean but dramatic minimal look when she did the red-carpet rounds for The Girl With The Dragon Tattoo in 2011. Skip to 2015, Rooney was the talk of Cannes as she was named Best Actress, tied with the French actress Emmanuelle Bercot.
Rooney said about the award: "I am incredibly honored and thankful to have been recognized by the Jury at the Cannes Film Festival for Carol. I knew that Phyllis Nagy's adaptation of this story was something special, but what Todd did with it is beyond anything I could have imagined."
She added: "Working with Cate [Blanchett] really was a dream come true. And everyone involved with making the film, who worked so hard to make sure the film could see the light of day. I just feel lucky to have been a part of it."

We are jumping ahead here, but we are using this as a sign that Rooney Mara has many red carpet appearances ahead of her (we're talking Golden Globes, SAGS, Oscars).
Whenever Rooney hits a red carpet we have the sudden urge to cleanse our wardrobes, and get out some black eyeliner. When it comes to fashion Rooney is loyal, wearing exclusively white and black, no jewellery and clean lines.
At Cannes she wore a white lace Victorian Alexander McQueen dress to the 'Carol' photocall and a white silk halter Olivier Theyskens for Roachas gown, with an embroidered ruffled train.
Rooney, it's good to have you back.
