Sienna Miller wants Keira Knightley to be the face of her fashion line.
The 25-year-old star thinks her actress friend - who she met on the set of their new film 'The Edge of Love' - would be the perfect muse for the clothing company, Twenty8Twelve, she runs with her fashion designer sister Savannah.
Speaking at the London premiere of her new movie 'Interview' last night (18.10.07), she told BANG Showbiz: "I'm not thinking of a face for our brand yet but I would love Keira. I love her face!
"That's quite a good idea, right - I'm getting Keira."
Sienna - who looked stunning in a black Alexander McQueen dress and Chanel diamond jewellery - joked it would be a bit of step down for Keira, who is already the face of designer fashion house Chanel.
She added: "She is the face of Chanel so she is not going to come and do my little line. I could bully her into it. She is my mate, so you know, mate rates and all that, we will see."
The star - who stars opposite Steve Buscemi in 'Interview', which sees her play a TV actress - remained coy on her relationship with actor Rhys Ifans, who turned up to show his support for her last night.
When somebody commented on seeing Rhys arrive, she replied: "Oh, did you, yes!"
Sienna also revealed she would not be living up to her party girl reputation at the after-show party, because she was suffering from an abscess in her tooth.
She added: "I am looking forward to it, but I can't really party all night.
I've got an abscess in my wisdom tooth, which is why I'm a bit sombre tonight, so I can't really drink, because I'm on antibiotics." |
