Preview - Gotham City Sirens #6

When you get Harley Quinn, Poison Ivy and Catwoman together you know that things will be mischievous. In Gotham City Sirens #6 the lovely threesome are faced with Mr. J's secret out in the open. What's the secret? Well, it's enough to jar Harley who adores Joker. Paul Dini and Guillem March are working on the sixth issue which hit stores last week (it might've gotten lost in the Thanksgiving fold). Enjoy a preview after the jump, courtesy of DC's The Source.
