Louis Tomlinson and Niall Horan were snapped living it up at London's Libertine Club. The pair, joined by the lovely ladies from American girl group Fifth Harmony, partied till the early hours of the morning at the celebrity hotspot. Newly single Louis was spotted heading off in a taxi with Lauren Jauregui. He certainly didn't waste much time before moving on. While Niall, who left just after Louis, was joined on his journey home by a mystery lady.
