Louis Tomlinson - the oldest member of One Direction - starred in several musical productions while studying for his A Levels at local comprehensive Hall Cross School.
He auditioned for The X Factor in 2010, performing the song Hey There Delilah by the Plain White T's.
Failing to qualify as a solo contestant, he was later put into boy band One Direction. Louis Tomlinson joined Harry Styles, Niall Horan, Zayn Malik and Liam Payne.
1D proved extremely popular with the public and ended up coming 3rd in the competition. They gained thousands of fans while competing in Simon Cowell's talent contest.

They've had a number of No 1 singles, such as What Makes You Beautiful, Little Things and Comic Relief hit One Way Or Another (Teenage Kicks).
Louis' private life has been scrutinised by fans. Some very vocal Directioners are fixated on the imagined romance between him and Harry Styles. They refer to the boys as Larry Stylinson.
Louis has vehemently denied the rumours and Harry followed suit when a reporter asked him outright if they're an item.
When he made Eleanor Calder his girlfriend in 2011, Louis proved that he prefers ladies. They have always tried hard to make their romance work, despite his busy schedule.
'Obviously it's not easy having a long-term relationship in this job, but it frustrates me when people say it's impossible,' said Louis in 2014.
'It's definitely doable, it's down to the people and whether they want to make it work enough.'
