Although there is one thing that her repertoire is lacking.

She doesn't have a lot of musical collaborations.

While she has worked with the likes of iconic musical geniuses like Hans Zimmer behind the scenes and is constantly collaborating with her brother Finneas, she has only once performed on a song alongside another artist.

Her song 'Lovely', which features Khalid, has been her one and only collab.

Until now.

While there have been subtle hints, she has finally announced that she will be releasing a new single with another songstress who burst onto the scene and, just like Billie, is showing no signs of stopping any time soon.

Working on the single, the duo were set up in their separate homes and worked with what they had in their makeshift studios.

She is known for putting her own spin on the flamenco music-style, has won a Grammy Award, has won multiple Latin Grammy Awards, and Pharrell has invited her to his studio to work on some music.

She was also the only musician featured on Time's 2019 list of 'Next Generation Leaders'.

Sure, you might not be able to understand all her lyrics, but there is no denying that you'll be dancing along to her tunes and singing along the parts you do pick up because this girl is talented.

And thanks to both of these women for giving us the collab we didn't know we needed!
