Thirteen-year-old Rebecca Black went global earlier this month when she posted her home-made, heavily auto-tuned music video.
It sparked a media frenzy, attracting thousands of critical comments and earning her the title of "worst singer in the world".
But the teen needn't worry, as it appears she has the approval of music mogul Simon Cowell.
When asked about the song, entitled Friday, the 51-year-old said: "Love it!
"I've never seen anything cause so much controversy. I think it's genius. The fact that everyone's getting upset about it is hysterical.
"It reminds me of Saturday Night… It's what we call a 'hair dryer song' – a song girls sing into their hair dryers as they're getting ready to go out.
"But the fact it's making people so angry is brilliant."
