The musician, 21, real name Harvey Leigh Cantwell, joins a line-up that includes actress Caroline Quentin, comedian Bill Bailey and reality star Jamie Laing.
“I’m proper nervous but I’m buzzing. I don’t think it’s the dancing – it’s the tight shirts and the tight trousers,” he told Kiss Breakfast with Jordan & Perri.
He said: “I’ve grown up watching it. I can’t wait for the challenge.
“I really want to win… If I go out on the first week I’ll have to change my name and leave the country!”
He said he felt confident: “I’ve got it in me… My hips can move!”
The star added in a statement: “Being on Strictly is going to be such an amazing experience and I’m so thankful to be taking part this year.
“I think my mum is more excited that she’ll be able to see me every Saturday night now.”
The former presenter of CBBC’s Friday Download, HRVY was born in Kent and first rose to fame after uploading his music videos to Facebook.
