The 25-year-old actress recently talked to THR about the CW drama, which reached its 100 episode milestone.
“I started auditioning back in December 2006. The process was really long. At the time, I wanted to move to New York, but I didn’t have a reason or any money. So when my agent sent me the Gossip Girl script, I thought Blair was perfect for me,” Leighton shared.
“Originally the script had my character suffering from an eating disorder,” she added, “but they ended up taking it out.”
