Charli XCX is a genius: Debbie Harry

Blondie frontwoman Debbie Harry has heaped praise on Charli XCX after she wrote a song for the band's latest record "Pollinator".

The veteran singer called the "Boom Clap" hitmaker, who penned "Gravity" for the band's latest album, an outstanding songwriter, reported Contactmusic.

"She's a virtual genius. She told me she wrote 'Gravity' when she was 15 - honey, when I was 15, I could only dream of writing a song like that.

"But she's really got something. When you listen to her lyrics, it's clear she's been exposed to some really interesting literature. She has a frame of reference that's very large - which is either because she's read a lot or she's had many different lives, which is a nice possibility," Harry said.
