Alex Turner and Alexa Chung met at a festival in 2007. There are different accounts about which festival it was, but the most common one is that they met at the Glastonbury Festival.
It's said they met at the festival's "Shangri-La" area, known for its quirky and alternative installations. The exact circumstances of their meeting remain a bit of a mystery, but it's clear that they hit it off and began dating shortly after.
