Blake Lively Almost Never Signed On
We could not imagine anyone else in the role of Serena, but the actress was initially hesitant to join the series. Lively's work on The Sisterhood of The Traveling Pants.
"We didn't see a lot of other girls for Serena," series creator Josh Schwartz said.
"She has to be somebody that you believe would be sitting in the front row at Fashion Week eventually." Lively later relented after first declining when she was told she could attend Colombia one day a week.
It was never put in writing and it sure sounds like Lively did not get to go.
"This is advice to anyone: when they say, 'We promise, but we can't put it in writing,' there's a reason they can't put it in writing," Lively said with a laugh, "But no, the show didn't slow down. It just got more and more."
Chace Crawford Did Not Think Leighton Meester Was Right For The Show!
Leighton Meester was AMAZING as Blair Waldorf, but Chace Crawford seemed to think she was not the right person for the role.
"I just don't see her as Blair Waldorf. I can't see it," he said of Meester. But he saw it immediately when she got into character, thinking, "That girl can act. She's the perfect girl for this."
Schwartz said, "Obviously; Serena had to be blonde. So, [Leighton] went to the sink and dyed her hair. She wanted it."
Who Did Meester Originally Audition To Play?
Leighton originally auditioned as Serena, but she managed to convince them she would make a better Blair.
"I think it was just the normal, typical pilot season audition for me. I auditioned and then I tested once and then we did a screen test with everybody. And then, that was it ... I dunno. I got it," she said.
Did Leighton and Blake Hate Each Other?
Like any popular TV series, there are always rumors that there is unrest on the set between the stars.
"When we were filming, there was, 'Leighton hates Blake, Blake hates Leighton, everyone hates Blake, everyone hates Leighton, everyone hates Chace,' and blah, blah, blah. It really wasn't," Michelle Trachtenberg said of the energy on set. "We were all chill. It was cool."
Were They BFFs?
While Leighton and Blake may have gotten along, they were not as close as Serena and Blair.
According to executive producer Joshua Safran, "Blake and Leighton were not friends. They were friendly, but they were not friends like Serena and Blair. The second they'd be on set together, it's as if they were."
Why Did Ivanka Trump and Jared Kushner Appear?
We already knew that Ivanka was a huge fan of Gossip Girl, but fans were surprised when she actually made an appearance on the show, but why did she take on a role?
"They did it for the money," Schwartz revealed with a laugh. Yes, we're going to bet he's totally kidding.
