WWE superstar Becky Lynch is already dreaming of "WrestleMania" dominance -- telling us she's dying to "slap the head off Ronda Rousey."
Lynch was supposed to battle Rousey at "Survivor Series" back in November -- but she suffered a serious injury to her face and was pulled from the match.
But, Lynch says she still has a sense of "unfinished business" with Rousey ... and wants to settle things once and for all on April 7 at MetLife Stadium.
Despite the rivalry, Lynch praised Rousey for all that she's done for women's pro wrestling, women's judo and women's MMA .
