sienna millerSienna Miller has revealed that her relationship with Rhys Ifans has had a rather negative effect on her bum.

She told Elle magazine recently: “It wobbles when I walk. Seriously. I have a lardy a***. Some days I look in the mirror and go ‘Yuk’.”

She explained that she’s piled on the pounds recently and they’ve all gone to her posterior: “Our lives revolve around food. We are both totally obsessed.”

She added that the couple are hooked on pickled onion Monster Munch crisps and French fries dipped in chocolate milkshakes - but their main love is something a bit more fancy: “We have this horrible addiction to caviar, which sounds ridiculous but it’s true. We’re junkies.

“We do the whole works: blinis, chopped eggs, chopped red onion, sour cream… it’s total bliss.”
