There is no better publicity than starting a celebrity (fashion) feud. And that is just what Sienna Miller seems to be doing by launching a "scathing attack" on fellow style queen Kate Moss' Topshop collection. Sienna's collection Twenty8Twelve which she is launching with designer sister, Savannah, is due to be released soon and with all the comparisons being drawn in the media about the two collection, Sienna argues that their respective collections are completely different.

Miller says, "Her clothing project was very different with ours. Obviously I would say this, but actually my sister and I started to work on ours before she did, two and a half years ago. And also, unlike Kate Moss, Sav is a real stylist."

Ouch! What do you think?
