Lady Gaga has released a teaser video for her upcoming performance at this year's MTV Video Music Awards (VMAs).
The video, which can be watched below on Gigwise, sees the singer performing new single 'You And I' playing the piano and removing her bra.
In the voice-over she says: ''Sometimes I'm really happy when I write music; sometimes I'm really angry, sometimes I'm really drunk, or sometimes I'm super-sober. You never really know why, if or how you write music."
The ceremony will take place at the Nokia Theatre in Los Angeles on August 28 and will be broadcast the following day in the UK.
Lady Gaga joins a line-up of performers that already includes Adele, Bruno Mars, Lil Wayne, Chris Brown and Young The Giant.
As previously reported on Gigwise, Katy Perry looks set to dominate this year's MTV Video Music Awards (VMAs) after collecting nine nominations.
The singer is nominated for all the major awards, including Video Of The Year' for 'Firework', Best Female Video and Best Pop Video.
