British actress Sienna Miller wants Keira Knightley to be the face of her new fashion label Twenty8Twelve. The pair bonded on the set of their recent film The Edge of Love and have remained close friends ever since. Miller launched the clothing range, a joint venture with her sister Savannah, in August (2007) but hasn't yet found a suitable model to front the collection. Speaking at the premiere of her new movie Interview on Thursday night (18Oct07), the star insists she would love to get the Pirates Of The Caribbean actress on board but won't be getting her hopes up. She says, "Oh god Keira - I would love it. She's the face of Chanel so she's not likely to come and do my line. But she's my mate so hopefully I'd get mates rates. I would definitely love Keira to do it. I love her face."
