Patrick Dempsey was forced to wear a kilt for new movie Made Of Honour, but had to shun tradition and put on some underwear after his private parts were attacked by insects.

The Grey’s Anatomy star was filming in Scotland and was happy to don the country's native dress, which is often worn without undergarments.

Dempsey was determined to wear his kilt in an authentic manner, but found himself covered in bites from local winged flies - forcing him to go back to wearing underwear to protect his most delicate area.

He says: "I wore a kilt for the wedding scenes, but had to wear something underneath. I tried nothing but I was bitten all over by midges."
