"Thinking about the show on the way home last night, it struck me how hard a worker Jessie J is. And a perfectionist too."

The 405's Mathew Parri Thomas headed south to spend some time with Jessie in the lead-up to her show at the O2 Academy Brixton. From devoted fans (who camped out 25 hours before her performance), to the adrenaline-fuelled walk from dressing room to stage, this gallery has it all.
