Movie star SEAN PENN is piling on the pounds (kilograms) and chewing his finger nails in a desperate bid to stay smoking free.

The DEAD MAN WALKING actor quit smoking in August (00) - a 40th birthday gift to himself - and is struggling to stay away from cigarettes.

During a recent lunchtime interview with DETAILS magazine, Penn ate a fried calamari platter followed by a hamburger platter and admitted that his breakfast intake can be steak and eggs and home fries, coffee and a Coke. Food is not the only thing Details says Penn is gnawing on. His fingernails are bitten down to the quick.
