Remember back in June when Katy Perry decided to stream her life for FOUR DAYS straight ahead of her Witness album release? The goal was to show her fans the “good, the bad, and the ugly” as Katy put it. Of course we saw celebrities stop by and join Katy to hang out over the four day period. Depending on when you tuned in you may have seen some familiar faces like Mario Lopez, RuPaul, and even Gordon Ramsay. Chances are you had your own life to live though during that four day period, and didn’t catch all of these moments. Not tow worry! The best parts have been strung together into a new feature length highlight film Katy Perry: Will You Be My Witness? that will debut on YouTube Red October 4th! Watch the trailer below!
