“Hitting No. 1 is always a great moment, but when it turns into a small piece of history, you’re reminded of how many millions of people are connected to each other by even one tiny event. Thank you to everyone who helped make this happen,” Perry told Billboard upon learning of her achievement. “Ever since I was 9 years old, singing into my hairbrush, I’ve dreamed very big dreams, but today is bigger than my dreams.”
Meanwhile, Perry, aka, Kathy Beth Terry, wrangled a host of guests for the mini-movie video for “T.G.I.F.,” including Rebecca Black, Darren Criss, Hanson, Kenny G, Corey Feldman and Debbie Gibson (the latter two as her ’80s alter-ego’s parents … Kirk and Tiffany).
