Katy Perry continues to dominate the music charts and has now scored her ninth number one single.
"Wide Awake" just took over the top spot of the Top 40 chart.
Our beloved Katy is taking the world by storm with her fun, catchy tunes, single by single. The singer is currently in Brasil promoting her movie, Katy Perry: Part Of Me 3D. She was also just nominated for four MTV VMAs.
Congratulations to Katy!
