Leighton Meester, Blake Lively & Taylor Momsen (“Gossip Girl”)

Before the final season of "Gossip Girl" the gossip mill was passing around a story about the three female actresses "battling it out to be Queen Bee." Star Magazine reported that "they’re all lobbying for more screen time and the best plot lines for their characters … All three of them feel like their star is on the rise and don’t want the other two to surpass them.” Apparently things came to a head over Meester's increased costume budget. Lively maintained that the story wasn't true. [Gossip Cop]
