Charli XCX has shared a brand new collaboration with Tove Lo and ALMA called 'Out Of My Head'.

The 25-year-old singer has been teasing fans about a brand new mixtape with an all-star list of artists lending their talents, and now she's given them a taste with the exciting first track.

The star revealed to BBC Radio 1 that the upcoming record, entitled 'Pop2', will be released next week, and the fresh single will give fans an idea of what's to come from the exciting project.

Charli - whose real name is Charlotte Emma Aitchison - only released her third compilation 'Number 1 Angel' in March, but has hinted that she has also secured duets with Carly Rae Jepsen, Brooke Candy, Mykki Blanco and Tommy Cash to collaborate with her for the new project.

Writing on Twitter on Sunday (03.12.17), she hinted: ''imagine if i did another mixtape with @carlyraejepsen @tovelo @almacyber @cupcakke_rapper @brookecandy @pabllovittar @carolineplz @jaybumaom @kimpetras @dorianelectra @mykkiblanco tommy cash @momomoyouth and @agcook404... that would be pretty cool right..?? (sic)''

It would come as no surprise to Charli's fans as in 2012, the 'Boys' hitmaker dropped two mixtapes in the form of 'Super Ultra' and 'Heartbreaks and Earthquakes'.

Speaking about 'Number 1 Angel', the singer previously explained that it is ''essentially album'', although fans are still eagerly awaiting the official follow-up to 2014's LP 'Sucker'.

She said: ''It's 10 whole new songs basically. It's [being called] a mixtape so it can go out for free, but it's essentially an album, a whole new album.''

Meanwhile, Charli also admitted she had scrapped the tracks she'd worked on for her third full length album after it was leaked online.

She said recently: ''My email got hacked and people leaked most of it, so I think I'm just going to start again. But that's fun for me, anyway I write fast so I'm not really worried about anything.''
