The four piece girl group last month lent their pitch perfect vocals to a massive concert in their home country of the Philippines.
The girls hosted the 4th Impact Invas10n - celebrating a decade together - at the KIA Theatre.
And during the concert the group dropped brand new single Unleash The Diva.
The upbeat track is full of sass, just as we'd expect from the pint-sized popstars.
4th Impact revealed at the concert that the song would be available to download worldwide from iTunes and it's available NOW to download HERE
4th Impact originally left The X Factor judges stunned during auditions on the show back in 2015.
Or rather 4th Power as they were known then.
The family from the Philippines flew half way around the world to sing in the competition, mainly lured by the prospect of seeing Simon Cowell.
Oh, and our Queen.
Made up of Mylene, Celina, Irene and Almira, 4th Impact are sisters who may have looked like the picture of sophisticated grace but stunned with a powerful performance of Bang Bang by Jessie J, Ariana Grande and Nicki Minaj.
There were dance moves, hair flicks and even rapping as 4th Impact rocked the stage to leave the X Factor judges overwhelmed with an audition that's since been watched 65 MILLION times.
It makes it the second most watched X Factor audition in HISTORY, behind only Abilisa's infamous on-stage punch up.
4th Impact went on to finish fifth in The X Factor last year and wow in the show's live tour earlier in 2016, which you can also relive in our video above.
