The upcoming DC spinoff "Birds of Prey" just got an official, full title -- and it's both fantastic and fabulous.

Star Margot Robbie took to Instagram to reveal the moniker, sharing a picture of the film's script with a scribbled subtitle. It reads in full: "Birds of Prey (And The Fantabulous Emancipation of One Harley Quinn)."

Warner Bros. also shared the image on Twitter, though some fans remained skeptical that this was indeed an official subtitle. But The Hollywood Reporter did some digging and confirmed that this is indeed the actual name of the movie, "and not just the star having some fun" doodling on her script.

It's clear, though, that Robbie and co. are indeed having fun with this production, which is being billed as an R-rated girl gang romp. As THR reports, the title suggests that the flick will center at least in part around Harley's (Robbie) breakup with the Joker (played by Jared Leto in "Suicide Squad," from which "Birds of Prey" is spun off), as portrayed in a recent comics storyline.

In addition to Robbie, the titular heroines and villainesses include Mary Elizabeth Winstead as Huntress, Jurnee Smollett-Bell as as Black Canary, Rosie Perez as Renee Montoya, and newcomer Ella Jay Basco as Cassandra Cain. Ewan McGregor plays the villain, Black Mask.

"Birds of Prey (And The Fantabulous Emancipation of One Harley Quinn" is due in theaters on February 7, 2020.
