Brand debuted his the new inking with the words 'Lord, make a channel of thy peace', scrawled across his right arm, reported Daily Mail.
The line is from the Prayer of St Francis, and it appears in an Alcoholics Anonymous book called 'Twelve Steps and Twelve Traditions'.
The funnyman and actor, who has conquered his addiction demons, has got a daily reminder to ensure he never goes back to those dark days.
He was spotted walking the streets of Los Angeles in bare feet and showing off the inking. The British A-lister stepped out in ripped jeans, a grey singlet top and black vest.
His new body artwork comes after he recently revealed that he would still rather be a drug addict instead of an international superstar.
During filming of a television documentary, the 37-year-old watched footage of his twenty-something self smoking heroine in a dirty Hackney flat and admitted that he missed those days.
