If you had a nickel for every sexual innuendo in Katy Perry's latest single 'Birthday', you would have a lot of money. She's premiered a new lyric video for the track just in case you missed a few of them, and a fair warning: those of you with a sweet tooth will probably find yourselves tracking down a cupcake or two once you're done watching it. The 'Birthday' video is, fittingly, filled with all kinds of cute and colourful pastries and baking products. The song is taken from her most recent album Prism, and you can catch her kicking off the Prismatic World Tour on 07 May at the Odyssey Arena in Belfast.
