" Lady GaGa has teased her upcoming performance at the MTV Video Music Awards with three short promos.  The Born This Way singer can be seen in the black-and-white shorts performing her new single &amp;#039;You And I&amp;#039; while sitting at a piano surrounded by a jazz band. At one point she removes her bra but then covers her modesty with a sheet of music.  In the voice-over she says: &amp;quot;Sometimes I&amp;#039;m really happy when I write music; sometimes I&amp;#039;m really angry, sometimes I&amp;#039;m really drunk, or sometimes I&amp;#039;m super-sober. You never really know why, if or how you write music.&amp;quot; Watch Lady GaGa&amp;#039;s MTV VMAs promo below:       GaGa will also make an announcement about the VMAs during a live appearance on MTV and Logo&amp;#039;s MTV First: Lady GaGa on Thursday at 7.49pm ET/PT.

She has also been named in the brand new &amp;#039;Best Video With A Message&amp;#039; category for her &amp;#039;Born This Way&amp;#039; promo, with MTV saying it &amp;quot;promotes a world free from prejudice, judgment and self-doubt&amp;quot;.
