| Filed under: Music MinuteYouTubeKaty PerryReality TV

Katy Perry is pulling out all the stops to promote the release of her new album Witness.

In an experimental stunt, the pop star is spending the entire weekend in a house filled with cameras, Big Brother-style, livestreaming her every waking hour on YouTube!

But she isn't just reading magazines and cooking ramen; she's spending the time interviewing fascinating people. So not at all like Big Brother. Ha!

Oh, did we say every waking hour? It's every sleeping hour too. The cameras will just keep on rolling all through the weekend leading up to an exclusive FREE concert for 1,000 fans in a very secret location on Monday night.

So cool! Just don't stay in the house too long, gurl — it makes you crazy!!! Ha!
