Lady Gaga previews two new songs 'Manicure' and 'Swine'
Check out the two minute-long videos of "Manicure" and "Swine," both upbeat and possibly silly.
Its expected that Lady Gaga will perform her current single "Applause" at the concert; the event will be live-streamed via the iTunes Festival London 2013 application via (you guessed it) Apple. "Applause" arrived ahead of her new album "ARTPOP," due Nov. 11.
