Throughout Oscars Night, we saw commercials saying that Britney Spears had big news to reveal on Good Morning America.
The 'Femme Fatale' was on the morning show on Monday, and revealed the 'big news' herself.

Check out the video after the bump:

The star announced that she will be performing for the first time ever in a special concert in San Francisco on "Good Morning America" on Tuesday, March 29!

Is it just me, or does Britney sound like she got testosterone injections? Or a really nasty cold?
