Katy Perry was spotted making her way to the ‘Jimmy Kimmel Live’ studios in Hollywood, California, yesterday to promo her docu-movie ‘Katy Perry: Part of Me 3D’.

When Jimmy asked how she got her hair so purple, Katy said, “I squeeze the purple Teletubby all over my head [and] I go out [in the rain].”

Sporting sky-high Christian Louboutin black-platform slingbacks, the singer wore a Temperley London Fall 2012 dress.

Her purple hair almost blends into her dark floral-print frock with long sheer sleeves.

Katy appears to have taken a more sophisticated, grown-up approach to this promo tour, but I hope we see her fun side at the movie’s LA premiere later this evening.
