No one works harder than me, says Gerard Butler

London: `PS I Love You` star Gerard Butler insists no one works harder than him.

The 43-year-old actor checked into a rehab centre last year to tackle his addiction to prescription drugs, but Butler said he used the substances because of his heavy work load, reported Contactmusic. "I`m no angel but there`s no one in this world I think that works harder than me," he said. Butler took up smoking again two months ago but remembers how overwhelming the smell of smoke was during his cigarette-free period. "I really noticed the smell of people when they smoke and it especially comes from your fingers. I can shake up to 500 hands in one night and those people ... Some of them are clean, some of them are dirty," he added. PTI
