The revelation was made on the official Nutella website in the Frequently Asked Questions section.
Under 'What is Nutella hazelenut spread?' the company wrote: "Nutella (pronounced "new-tell-uh") is a tasty, unique spread made from the combination of roasted hazelnuts, skim milk and a hint of cocoa. Nutella has no artificial colors or preservatives."
Fans took to Twitter to express their surprise.
Many were shocked by the fact the first syllable of the word is not 'nut' even though the spread contains hazelnuts.
Outraged fan Makayla said: "I hate it when people pronounce nutella as newtella. It's NUTella. It has hazelNUTS in it. Stop."
While user Pip Roberts added: "So I just found out Nutella should be pronounced new-tella! Ok so my life has been flipped upside down! Don't even know what's real anymore!"
