Blake Lively and Penn Badgley share some hot kisses - July 7 2009

Blake Lively Poisoned Badgley
Blake Lively has admitted that she "poisoned" her fellow castmates against co-star Penn Badgley.

She told Glamour that she was "so upset" to learn that Badgley had been hired for the role of her on-screen boyfriend.

"At first I was so upset that they hired him. I actually poisoned the whole cast against him," she explained.

"But then they noticed that he was not a jerk and was actually a really nice, charming person. Almost immediately I realised that too, but it took me about a week to admit it."

Lively and Badgley, who are dating in real life, first met when the actress was just 11-years-old.
