Katy Perry visited ‘TV Total’ last Monday, talking with host Stefan Raab. The singer gave Stefan a present – a microphone – and discussed her prior visit, where she confused the host with a sound tech after performing ‘I Kissed A Girl’ and handed him her microphone, not knowing he was the host. Perry said she got confused because Stefan wasn’t dressed up like a proper host. She then talked about meeting the Pussycat Dolls, who also all jokingly handed Stefan their mics after learning about Katy’s flub. The clip ends with Perry learning how to say her ‘One Of The Boys’ album title in German. Video at tvtotal.prosieben.de has since been removed.
