Her paternal grandparents cared for Meester during this period. She has maintained that her parents gave her a normal upbringing and, despite their criminal past, has stated, "It made me realize that you can't judge anyone—especially your parents—for what they've done in their past, because people change."

2007–2013: Gossip Girl and music ventures

She first auditioned for the role of Serena van der Woodsen, but told the producers she could better play Blair.

Her performance was the most critically acclaimed of the show, with Blair being cited as the series' breakout character. She also garnered media attention for her wardrobe on the show. The series ended after six seasons and 120 episodes. Meester later starred in the television film The Haunting of Sorority Row, and had a role in the ensemble comedy-drama film Remember the Daze (2007).

She then starred with Gwyneth Paltrow and Garrett Hedlund in the country music drama Country Strong (2010). Wesley Morris of The Boston Globe described Meester as the best part of the film, writing, "She's just doing Reese Witherspoon's June Carter Cash in Walk the Line with dabs of Miley Cyrus and Kellie Pickler. But it's not an impersonation; it's a performance with its own comedy and sweetness." Claudia Puig of USA Today was also positive, stating "Meester shows she can do more than play one of Gossip Girl's privileged Manhattan socialites." For the film, Meester recorded a cover of the song "Words I Couldn't Say" by Rascal Flatts as well as "A Little Bit Stronger" by Sara Evans featured on the film's soundtrack; a promotional single titled "Summer Girl"; and a duet with Garrett Hedlund titled "Give In To Me". After wrapping, she received a guitar from Tim McGraw and decided to learn how to play it. In October 2010, Meester said she had been working with a band called Check in the Dark and had been writing for the last six months after being inspired by Country Strong. She revealed her influences, saying, "I love Neil Young and Joni Mitchell, that style of music, and as far as songwriting I think that's where my heart is."
