Her Gossip Girl cast did NOT hate her!
Like I said; Taylor was like 14 when the show first started and the rest of the cast was like 20.
She didn't have a feud and didn't have a rivalry with anyone. Those are just rumors. She was probably like acquaintances with Blake and Leighton.
She was only close with the people who played her family;
Matthew Settle (dad on the show), Penn Badgley (older brother on the show), Connor Paolo (step-brother/best friend on the show) and Kelly Rutherford (step-mom/Serena's mom on the show). Taylor was very friendly with them and they were (and still are) very supportive of her.
This is what Leighton Meester said about Taylor around a month ago:
"She's so talented, and anyone I know that's heard her music is a huge fan," she shared. "You can't help it. She's also an incredible actress and just a lovely girl."
Around a week or two ago, Penn Badgley says that he misses Taylor and that he wishes she was still on the show, and that she is kinder than what people give her credit for. He also said he'd like to get in touch with her.
I think Nicholas Sparks is a terrible author
