If there's anyone who knows a thing or two about doing a fantastic collaboration with another artist, it's Charli XCX. From her insane hook on Iggy Azalea's 'Fancy,' to the huge success of Icona Pop's 'I Don't Care (I Love It)' to the indie cred she garnered when collaborating with Marina and the Diamonds on 'Just Desserts,' it's safe to say Charli knows exactly what she's doing.

This time, Charli is releasing a new version of her own track, with someone else as the feature artist. Her latest single is a slightly remixed version of her song 'Doing It,' straight off her sophomore album, 'Sucker.' But the version Charli's releasing is slightly different from the cut on her album. She teamed up with Rita Ora to mix things up a little, and we're totally loving it.

Charli starts in on the track like normal, and then Rita comes in on the second verse, adding her signature powerhouse vocals to the track. We have to admit -- as much as we love the original, we're seriously loving this version of the track. There's something about two totally talented women mixed with all that attitude that makes the track equal parts fun and exciting.

Check out the remixed version of 'Doing It' above and let us know what you think!
