Katy Perry: Polka Dot Pretty

Plugging away at a busy day of promos, Katy Perry was spotted leaving BBC Radio 1 Studios earlier today (September 2).

The “Teenage Dream” singer looked spectacular in a blue with white polka-dotted high-cut dress accentuated with a red flower as she stopped and posed for pictures.

Keeping her followers up-to-date, Ms Perry tweeted, “I'm about to get controlled @radio1... Sh*ts gonna get CrAzY!”

Earlier this week, Katy’s album "Teenage Dream," replaced Eminem's "Recovery" atop the Billboard 200 album chart.
