Watch: Katy Perry hilariously exposes a super-fan connected to lie detector [video]

Ever wanted to meet your favorite celebrity, not just your favourite but the one you are absolutely obsessed with. We all have or had that one growing up, some of us though, never quite grew out of being a super fan.

Katy Perry is in the UK doing promo for her latest single “Chained to the rhythm” and has been doing interviews at all the big radio stations.

The questions got tough and the fan got exposed on more than one occasion. Check it out below.
