UFC Women’s Bantamweight Champion Amanda “Lioness” Nunes makes the first defence of her title on December 30th at UFC 207 in Las Vegas, Nevada. Nunes is set to face off against former long-time champion “Rowdy” Ronda Rousey, who makes her return to action in the main event matchup.

UFC President Dana White announced the fight tonight. Nunes captured the title in July with a dominant first-round submission victory over then-champ Miesha “Cupcake” Tate. Rousey steps back into the Octagon for the first time since suffering a brutal loss to Holly “The Preacher’s Daughter” Holm.
