The 2011 MTV Video Music Awards are only 10 days away, and up until now the buzz surrounding this year’s show has been pretty quiet.

There’s no host, and while Adele and Lil Wayne are both entertaining as performers, they don’t exactly make for can’t-miss television. In fact, up until recently, the biggest thing the VMA show had going for it was the planned tribute to Britney Spears.

But Lady Gaga hopes to change that. MTV announced yesterday that the woman with the biggest album sales week of the year will be performing at the show, which will take place Sunday, August 28, at the Nokia Theater in Los Angeles.

What’s more, MTV unveiled a trio of promos starring Her Ladyship, all of which feature her sitting at a piano playing a jazzed-up version of “Yoü and I” (which, in unplugged form, borrows a bit from 4 Non Blondes’ “What’s Up,” doesn’t it?).

In one of those promos, she’s playing topless and lets her hair do a poor job of being her bra. Check out all the promos after the jump:

Gaga will be on MTV tonight for the television premiere of the new video for “Yoü and I” (it was supposed to be the first time anybody had seen it, but it leaked earlier this week), and MTV promises that there will be another big announcement from the Gaga camp.

Is it about a new tour? Will she be participating in the Britney Spears tribute? Will she be playing the VMAs covered in nothing more than seaweed and body glitter? If you’re curious, you can tune in tonight at 7:49 P.M. (how generous of them to give the last 11 minutes of a rerun of The Challenge!) for MTV First: Lady Gaga.

What do you think Gaga’s big announcement is going to be? What do you think of that jazz-cat arrangement of “Yoü and I”? And are you now more excited for the VMAs? Sound off in the comments.
