It was reported earlier that the 'White Flag' singer had questioned Rihanna's ability to write good music as she releases albums so often.
She was quoted as saying: "Rihanna seems to release a new album weekly. Unbelievable!
"When does she have time to write her songs? I could never release music that means nothing to me."
However, the 41-year-old singer has denied the reports on Twitter.
She said: "Obviously i didn't say that about rihanna!! i'm a big fan of hers! ridiculous. totally misquoted."
"It's so disappointing when the odd journalist still tries to pit female artists against each other. I love @rihanna. x"
Dido is set to release her new album The Girl Who Got Away on March 4 and spoke to Digital Spy about the record.
On the album's sound, she said: "Occasionally I wished that I experimented more, but I don't with this one - it represents all the kinds of music I'm into at the moment."
