Yes, she cheats

Ivy sees that Harley is in serious trouble. She crawls quickly through the ropes, running up behind the unsuspecting Catwoman and throwing a field-goal kick into her crotch. Catwoman lets out a horrifying half scream, half groan as she collapses beside the still winded Harley. Ivy starts to stomp at the fetal Catwoman as Batgirl climbs into the ring as well.

Batgirl catches Ivy off guard with a number of punches to the face and breasts. An uppercut to the chest causes her tits to bounce uncontrollably as she falls over backwards. Batgirl looms over her, with both Harley and Catwoman still to exhausted or beaten to stand.
