The singer unveiled the ethereal cover art, photographed by Ryan McGinley, during an appearance on US breakfast show Good Morning America today (6 September).
Katy will release Prism, the follow-up to smash records Teenage Dream and One Of The Boys, on 21 October.
Her album artwork reveal came a day after she released the jungle-tastic music video for 'Roar', which sees her crash landing in a rainforest and having to survive – while singing and looking nothing less than amazing, of course!
'Roar' has already shot to the top of charts around the world and is expected to enter the UK chart at number one this weekend as one of the fastest selling singles of the year.
According to the Official Charts Company, nearly 132,000 copies of 'Roar' had been purchased in the UK up until midnight last night.
It's currently 95,000 copies ahead of its nearest competitor, which is 'Burn' by Ellie Goulding.
