Charli XCX's teenage track makes Blondie album

Charli XCX has revealed she was just 15 when she first wrote the song that features on Blondie's new album 'Pollinator'.

The 24-year-old pop star features on the track 'Gravity' on the rock band's upcoming LP, and Charli has spilled that the tune has been nine years in the making.

She said: "It's a song I wrote when I was 15. I actually haven't heard their final version of it yet but of course I'm super-excited - it's Blondie, that's huge!"

Just as Charli has been delving into the past for new music, she also stepped back in time when it came to her fashion choice for the Diesel #MakeLoveNotWalls cocktail party which took place on Sunday (19.02.17) as part of London Fashion Week.

Double denim wasn't enough for the 'After The AfterParty' hitmaker as she opted for a three-tone denim dress for the exclusive bash, named in an apparent jibe at President Trump's policy idea to build a wall on the border between Mexico and the US.

As-ever, Charli oozed sex appeal on the red carpet and finished off her outfit with a pair of black heeled boots.

Charli was joined at the party by an array of stars, including supermodel Naomi Campbell, Ella Eyre, Conor Maynard and David LaChapelle.

The thirsty celebrities were able to satisfy their tastebuds with various Patron tequila cocktails including the Patrón Garden of Eden which is comprised of Patrón Silver, Jasmine tea, elderflower and fresh lemon juice spritzed with soda.

Music was supplied by DJs Charles Jeffrey, Jodie Harsh and Jonjo Jury.
