Charli XCX and Halsey Perform Spice Girls Classic 'Wannabe'

OMG. Charli XCX and Halsey have just made our biggest female duet dreams come true. Not only have they performed on stage together for the first time but they have also done an amazing cover of the Spice Girls' international hit 'Wannabe'.

YES CHARLI AND HALSEY JUST COVERED THE SPICE GIRLS!

The two performers joined forces at Lollapalooza in Chicago, Illinois this weekend.

Charli had her own 14 song long slot at the festival on Sunday. The 'Fancy' writer not only performed some of her biggest hits and critically acclaimed tracks but she also did a couple of renditions of pop classics and invited Halsey to join in.

AMAZING.

This isn't the only time that we'll be seeing the 'Boys' singer and 'Now or Never' hitmaker together though. Charli is joining Halsey on tour in the US in September, so we're hoping that the two of them have got some other big duets planned.

Ever the collaborative queen, Charli also invited up-and-coming rapper, Cupcakke, on stage with her. The two co-writers and friends slayed renditions of their Number 1 Angel track 'Lipgloss' together and Cupcakke's standout single 'CPR' too. 

Charli has also performed with popstars such as RAYE and Rita Ora this year.

We cannot wait to see who she works with next!
