Katy Perry Let's Them Eat Cake!

Face first! Ha!
Monday night, Katy Perry’s dancers, backup singers, husband and fans all sang Happy Birthday live to the superstar at Belfast’s Odyssey Arena. The crew brought out a beautiful cake for Katy to snack upon, but instead, she decided to share with the people who make it all worth while: the folks in the front row!
Check out the video (above) to watch Katy hit her fans upside the head with a massive cake!
A happy birthday indeed!
