Video/Photos: Lady Gaga premieres "Perfect Illusion" live to 250 people at secret London show

Late last night South London band Sweat played a show at the Hackney venue with many fans sticking around after rumours of Gaga's appearance circulated on Twitter.

Gaga took to the stage just before 1.30am this morning, following a DJ set from collaborator Mark Ronson - playing cuts from Kendrick Lamar, Missy Elliot, Mariah Carey and Tame Imapal as well as his own "Uptown Funk".

Performing new single "Perfect Illusion" live for the first time (albeit to a backing track), Gaga followed up with an extended solo piano version of "Bad Romance". She began "Poker Face" before going back for more of "Perfect Illusion".

Watch a video of the performance below.
