Demi Lovato arrives at WE Day California at the Forum on April 27, 2017 in Inglewood, Calif. 

Demi Lovato is prepping the summer's biggest house party. In a tease of her "Sorry Not Sorry" video posted on Tuesday night (July 18), Lovato asked "Hey @ParisHilton @iamjamiefoxx and @wizkhalifa are you ready for this one tomorrow?" The full video is slated to drop at noon on Wednesday (July 19). 

The color-splashed backyard bbq scene finds Lovato riding atop a stuffed bear and singing the song's soaring hook, dancing around in foam and shaking it along with a glittery sunglasses-wearing Hilton. 

Lovato is clearly enjoying the empowering, unapologetic vibe of the song, which she recently celebrated with a wild East Coast house part where she got a piggyback ride from New England Patriots tight end Rob Gronkowski. Last week she also kicked off her Sorry Not Sorry House Tour, which will find her performing a series of intimate gigs across the country for superfans.
