Arctic Monkeys' Alex Turner joins Mini Mansions on-stage in London

Last night (19th January) Alex Turner jumped on-stage with Mini Mansions to perform "Vertigo" in a rammed, sweaty and tiny venue in London. The Lexington hasn't seen a star this big (in the amount of albums sold) for a while, and it's been a while since Alex has performed a venue this size too.

Scroll on down to check out the performance. Alex will be on Mini Mansions' new album when it gets a release later on this year.
