Lady Gaga has released footage of her rehearsing two brand new tracks 'Swine ' and 'Manicure'

The popstar is currently in London ahead of her ITunes Festival gig on Sunday in the Roadhouse. Gaga is opening the festival which is in its seventh year. The ITunes festival runs for 30 days offering fans free gigs from acts such as Katy Perry, Robin Thicke, Avici, Elton John, Justin Timberlake and Ellie Goulding.

Gaga took to Twitter to debut the clips saying, 'The sound quality of these clips has been obstructed to give you a taste of ARTPOP but ultimately confuse you until Sunday. #SWINEFEST.' The singer has just released new single 'Applause' and is set to release her album 'ARTPOP' this year. She is also due to perform an hour of her brand new material on November 11.
