Louis Tomlinson sparked concern among parents of his impressionable young fans in May when a troubling video emerged of him smoking drugs on tour with bandmate Zayn Malik.

Liam wrote on Twitter: ‘I love my boys and maybe things have gone a little sideways I apologise for that. We are only in our 20’s we all do stupid things at this age’.
