Sienna Miller has won an award for her efforts to raise public awareness about global warming.
The 'Stardust' actress - who became an ambassador for Global Cool this year, an organisation committed to educating the public about the harmful effects of global warming - has been honoured with the Environmental Media Association (EMA) Futures Award.
Sienna will be presented with her prize at the 17th annual EMA awards ceremony, which airs on entertainment news channel E! on November 7.
The 25-year-old actress travelled to India in July this year to help publicise the Global Cool campaign.
She said: "We need to understand that we have to stand together and work together to conserve the bounty of nature. Hence, it is my sincere request to my friends, fans and citizens of India to do their bit to keep global warming from harming this beautiful country."
The EMA ceremony will also be attended by former US Vice President Al Gore who will collect the Outstanding Achievement Award.
Trudie Styler, Sting's wife, has won the EMA Lifetime Achievement Award.
Rockers Incubus will receive the Pepsi Mission in Music Award and penguin animation 'Happy Feet' has been named Best Feature Film for its "ecologically uplifting and informative message".
Meanwhile, Sienna's new love Rhys Ifans has asked her to marry him five times.
Sienna - who has constantly denied she is dating Rhys, despite the pair frequently being pictured together - isn't taking their romance seriously, while the 'Notting Hill' actor is "besotted" with her and desperate for them to wed.
A source said: "Their romance has been a big secret for months now. Friends believe Sienna sees the relationship as a bit of fun, while Rhys has fallen in love. Rhys wants the world to know but Sienna was keen to play it down - even though she usually flaunts her romances.
"He is besotted, totally in love. He can't believe his luck. He has already asked Sienna to marry him about five times but Sienna just laughs it off.
"His friends are worried that she will break his heart when someone better comes along."
Rhys, 39, has reportedly fallen out with his two best friends, fellow Welsh actors Ioan Gruffudd and Matthew Rhys, after they accused him of "stealing" Sienna from Matthew.
Sienna, 25, briefly dated Matthew in the summer after they met while filming 'The Edge of Love', and Rhys has been ostracised by his friends since he started romancing her.
The source added to Britain's Daily Mirror newspaper: "Rhys Ifans' name is mud among his former band of Welsh acting buddies. They all think it is disgraceful behaviour that he stole someone else's girl."
Sienna's close friends are certain the relationship will not last because Rhys parties too much and lives "like a student".
One friend said: "He blows everything he earns on going out and drinking. He lives like a total student. His place is a mess. He has lots of really weird habits." |
