For those who don’t know Katy Perry is a natural blonde.

You may remember she had red hair for a short time last month, which was a temporary measure before the singer returned to her roots.

She gave us the big reveal yesterday on MTV News.

Katy was there for the announcement of the nominees for the 2011 MTV Video Music Awards.

Wearing a striped Versus Spring 2011 dress the singer was excited to learn that she has nine nominations, including Best Pop Video, Best Collaboration, Best Direction, Best Special Effects, and Video of the Year for “Firework.”

The 2011 MTV Video Music Awards takes place on Sunday, August 28 from 9pm ET/PT on MTV.
