If you haven't heard Bonnie McKee's cahhhrazy mega-pop medley yet, you're probably living under a rock…
This particular version is extra special because Bon added in her new hit, Roar, and wanted our Perezious peeps to hear it first!
What an awesome V.I.P treat!
Ch-ch-check out the video (above) to hear her collection of jams, and listen close at the end where she adds Roar into the mix!
