American schoolgirl singer Rebecca Black has said that negative online comments about her music made her cry.
The 13-year-old's Friday video is currently a major internet hit with 29 million views so far on YouTube.
But the track has been heavily criticised online - with some newspapers and commentators dubbing it "the worst song of all time."
"When I first saw all these nasty comments I thought this is all my fault," she told US TV network ABC.
"[I thought] this was all because of me," she added, speaking on the Good Morning America show.
Rebecca said the worst post was someone who'd written "I hope you cut yourself and I hope you get an eating disorder so you look pretty. I hope you cut and die."
The video for Friday has has been trending continuously on Twitter and is notching up views at a rapid rate.
The single is also climbing the iTunes charts in the US and the UK and has entered the UK indie singles chart at number 10.
The track is about a teenager getting ready for the weekend but the lyrics have been widely ridiculed.
In one part of the song, Rebecca sings: "Tomorrow is Saturday. And Sunday comes after…wards. I don't want this weekend to end."
Others have criticised the use of autotune on Black's voice - that's a popular modern production technique which digitally alters singer's voices.
But Rebecca said the song was "catchy".
"Even for a person that doesn't like it, it's gonna be stuck in their head. That's the point of it."
Friday was made by producers at Ark Music Factory, a record label in Los Angeles that tries "to discover future #1 artists."
And despite the criticism, Rebecca is positive about the future - she even told ABC she'd love to record a duet with Justin Bieber.
"I have Bieber fever - I am in love with Justin Bieber. Would [he] do a duet with me? That would be unbelievable and make my life," she said.
She may also have a surprise fan with X Factor music supremo Simon Cowell telling People magazine in America that he loves the teen singer.
"I love her and the fact she's gotten so much publicity.
"I want to meet her. Anyone who can create this much controversy within a week, I want to meet. I love people like that," he said.
