Katy Perry: requested by Josef Zápotocky

There was certain time celebrity's just wanted to chill out and not deal with being famous.

But when you had a demanding career and demanding fans it was very hard to find the time.

So a lot of celebrities would employ somebody become their double to fill in for them when they could not do it.

Which was how 21-year old drama student Josef found himself turned into a copy of Katy Perry & filling in for her meeting and greeting her fans at a red carpet event.
