There may be a catfight brewing among next year’s Best Original Song nominees at the Oscars! The Blast reports that Cats stars Jennifer Hudson and Taylor Swift are both contributing new, original songs to the film’s soundtrack. There’s no info yet on what kind of songs they’ll be, but the outlet notes that T-Swift and J-Hud recorded their tracks separately and that the movie adaptation of the legendary Broadway musical will still feature most or all of its original score. Swift plays the cat Bombalurina in the film, while Hudson will take on the role of Grizabella–who famously sings the musical’s torch song, “Memory.” Cats also stars Jason Derulo, Idris Elba, Rebel Wilson, Ian McKellen, Judi Dench, and James Corden. It debuts in theaters on December 20.
