Niall Horan decided to ‘Live While We’re Young’ on Thursday night (13.11.14), going on a night-time bender at London’s Groucho Club in Soho, following One Direction’s stint on the Royal Variety Performance earlier in the evening. The 21-year-old star was joined by his mate, former ‘X Factor’ contestant Luke Friend for the party, with the pair stumbling out of the club at 2.30am.
