THIS IS NOT A DRILL:Rita Ora and Liam Payne are about to drop a duet.

The superstair pair have semi-announced an imminent collaboration that will lead the latest Fifty Shades soundtrack, a.k.a this is about to be 'huge'.

Following the worldwide success of the previous Fifty Shades singles, Rita and Liam have their hands on a guaranteed smash with this one.

Both stars posted a gorgeous promotional shot of them together on social media with the caption Fifty Shades Freed, the title of the final Fifty Shades film.

Rita is no stranger to the controversial movie series as she plays Mia Grey, the younger sister of the maincharacterChristian, so it makes perfect sense that she would soundtrack the last instalment.

Liam follows his ex-bandmate Zayn Malik's footsteps with the high-profile duet as his Taylor Swift collaboration 'I Don't Wanna Live Forever' soundtracked the second film.

Both 'I Don't Wanna Live Forever' and Ellie Goulding's 'Love Me Like You Do' dominated the charts around the world and we don't expect this to be any different.

We expect that this smash will be released with tomorrow's New Music Friday releases but will keep you updated on any details we find out...

Who's excited?
