(Cover) - EN Showbiz - James McAvoy steals thermal underwear from movie sets so he can wear it to bed.

The Scottish actor appears in this summer's Hollywood blockbuster X Men: First Class. He is married to Anne-Marie Duff and loves nothing better than returning home from a busy day shooting and snuggling up with her. However, James sometimes finds he gets chilly during the night, so has a novel way of staying cosy.

"Thermal underwear stolen from the wardrobe department," he replied, when asked what he wears to bed by the UK edition of InStyle magazine.

James added Anne-Marie is his only celebrity crush, explaining his idea of heaven would be to spend a weekend away at an isolated campsite with his 40-year-old spouse.

The 32-year-old actor also opened up about the first time he got romantic with a woman. He wouldn't say who the first lady he locked lips with was, only admitting it wasn't the earth-shattering event he'd hoped for.

"My first kiss was ruined, because there were too many boys in the next room," he admitted. (C) Cover Media
