Sienna Miller's milky chips

Sienna Miller is obsessed with fries dipped in chocolate milkshake.

The 'Edge of Love' actress, who is currently dating 'Notting Hill' star Rhys Ifans, revealed she regularly indulges her bizarre junk food cravings.

She said: "I have loads of food fetishes. Pickled onion flavoured Monster Munch crisps, chicken and stuffing sandwiches, milk chocolate with salt-and-vinegar crisps in your mouth at the same time. And French fries dipped in chocolate milkshake."

Sienna also says she and Rhys bonded over their food addictions and claims they are both caviar "junkies".

She added to Britain's Elle magazine: "Rhys is the best cook ever. He does these mad dishes that taste wonderful - like carrots poached in mandarin juice. Our lives revolve around food. We are both totally obsessed. I love to go home and cook.

"Rhys and I have this horrible addiction to caviar. We are junkies. I was given some seven months ago and now we have this full-on caviar habit. We do the whole works - blinis, chopped eggs, chopped red onion, sour cream. It is total bliss. Oh my god, it makes me sound so spoilt doesn't it?!"
