Aye, dios mios! The CW's charming telenovela Jane the Virgin is stirring up the drama again!

Rosario Dawson will be joining the back half of the fourth season of the award-winning series, The CW announced Sunday morning at the Television Critics Association winter press tour. There are zero details on her role or how she'll fit into the show, only that she'll be appearing in a multi-episode arc. And given the nature of the show, you can bet that her character will cause grief for at least one of your favorite characters.

Dawson adds to the list of fun guest stars on Jane the Virgin, which includes musicians Gloria Estefan, Britney Spears and Ke$ha, CSI: Miami's Adam Rodriguez, Gossip Girl's Kelly Rutherford and One Day at a Time's Justina Machado.

Dawson's previous credits include Josie and the Pussycats, Sin City, and Netflix's series of Marvel shows. She's also an activist and will be participating in the Time's Up movement — which brings attention to sexual harassment and abuse of power in Hollywood — at Sunday's Golden Globes.

Jane the Virgin returns Friday, Jan. 26 at 9/8c.
