Starting Thursday, the artist launched a 96-hour live stream —yes, including her sleeping through the night — to air through Monday, where she’ll be participating in a number of fun activities, hanging out with other celebrities and special guests and even performing songs from the new record in studio.

Already, Perry has cooked lunch with Gordon Ramsay, contemplated the universe with Neil deGrasse Tyson and had her makeup applied (or rather, her “face beat”) by YouTube star Laura Lee GLAM.

But there’s plenty more to come! The singer is set to host America Ferrera, Gigi Gorgeous, Sia, James Corden and many others through the whimsical weekend. See the full lineup, below, and Witness some highlights from the live stream for yourself.
