Rizzo rises again

I don't know what Sienna, on the red carpet for the premiere of her new film Casanova, is smiling about here. It's certainly not down to her outfit or hair. We know she cut her hair for an upcoming part as Edie Sedgwick in an Andy Warhol film so technically that's not her fault. The outfit, however, is. With the ill-fitting bustier and big earrings, she looks like an extra from a provincial stage version of Grease. And, for a whippet thin girl, she almost looks lumpy.

Given that Jude Law was seen slipping into screening before Sienna arrived, the smile tells you everything you need to know about her red carpet preparation. She clearly spent it on her back.
