Sienna Miller Is The Perfect Print-Cess On Jonathan Ross

Who?Sienna Miller.

What? Proving she really is a yummy mummy in a print-perfect purple, red and white Peter Pilotto minidress, Sienna wowed on The Jonathan Ross Show on Saturday night, where she revealed her godmother accidentally bought her a pair of crotchless knickers from Agent Provocateur and, soon after, she got pregnant...

Sienna was joined on the show by Jamie Oliver - who helped her and Ellie Simmonds cook up some festive treats - Michael McIntyre, Charlotte Church and Sheridan Smith.
