Sienna Miller's Pajama Party

Sienna Miller lets her dogs — Porgy and Bess — out for a walk, while still in her pajamas and slippers in London early Tuesday morning. Cute PJs!

In the rumor mill… supermodel Kate Moss is reportedly in a fight with Sienna over Rhys Ifans. Kate has been friends with Rhys for years and Sienna “stole him away.”

A spywitness at Saturday’s bash told The Sun: “Kate had a go at Sienna and accused her of stealing her style. She was ranting on about how Sienna was now trying to steal her lifestyle and her friends too. It was really cutting and everyone was listening to them. A few drinks had been sunk by the time Kate said it and Sienna had plucked up some Dutch courage too. She gave Kate as good as she got.”
