Katy Perry's music video for new single "E.T" has just premiered simultaneously on MTV.com and VEVO - The Dr Luke, DJ Ammo, Max Martin co-produced track serves as the fourth official single off 'Teenage Dream', the new *radio* version features rapper Kanye West, and it has just been announced as Billboard's new #1 song, giving Katy her fourth number one in a row! POWER TO HER! As for the new 'E.T' videoclip directed by Floria Sigismondi, it's SO outta this world! LOL, I had to say it. It's really great! Futuristic and in line with the song's vibe and title. High-budgetd, with freakin' cool costumes, FX AND story!.
