Lee Mack was born to John Mckillop and Christine Mckillop. He lived above a pub until he was 12 when his parents separated. There isn’t much information about his parents on the internet.
Mack became a Bluecoat entertainer at the Pontins holiday resort at Hemsby in Norfolk. He was sacked after appearing on stage drunk one night, forgetting a joke and insulting an audience member. He then worked for six months at Pontins in Morecambe.
Mack went on to have various other jobs and performed his first open mic slot in 1994, while studying at Brunel University, from where he graduated with a degree in Drama. Within 18 months, he was a full-time comedian.
Mack has taken part in several Soccer Aid matched to raise money for UNICEF. In September 2021, he scored for the first time, in a year that he played for the World XI team, due to his Irish heritage of his great-grandmother.
