They're the biggest boyband on the planet and last night 1D landed in the north east of England, kicking off the UK leg of their World Tour at Sunderland's Stadium of Light.
The boys now head to Manchester, Edinburgh and Wembley Stadium in London for more shows.
Martin was in Sunderland speaking to Directioners about the show.
