Too much caviar is giving Sienna Miller a 'lardy' backside!

London, May 30 : Sienna Miller has been eating so much caviar of late that she feels as if she's getting a 'lardy' bottom.

The actress reveals that boyfriend Rhys Evans got her hooked not only to the delicacy, but to food in general.

So much so that it's now taking a toll on her well-toned backside.

"It wobbles when I walk. Seriously. I have a lardy a***. Some days I look in the mirror and go 'Yuk'," the Mirror quoted her, as telling Elle magazine.

"Our lives revolve around food. We are both totally obsessed. "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."

Another of her favourite foods, she confesses, is pickled onion Monster Munch - and French fries dipped in chocolate milkshake.
