’One Tree Hill’ star Sophia Bush was all smiles for cameras as she posed along side her newest cast mates at the CBS/CW/Showtime Television Critics Association party on August 3. Bush attended the television event at the Huntington Library in Pasadena, Calif. to promote the seventh season of the CW veteran drama. Joining her was Austin Nichols, who has just been promoted to a series regular after appearing in the show’s sixth season, as well as Tree Hill’s newest residents Robert Buckley and Shantel VanSanten.

Buckley and VanSanten were brought in to fill the voids left by the departures of Chad Michael Murray and Hilarie Burton. Murray and Burton made their final appearance on ‘One Tree Hill’ during its’ sixth season finale on May 18.

Bush says that the loss of characters has given the show a chance to reinvent itself. “We closed a very large chapter of the novel that has been our show and we’re opening a new one”.

The new chapter will feature a one year time jump and give each of the show’s core originals a new sidekick. Robert Buckley will play Clayton, the NBA sports-agent to Nathan(James Lafferty), Shantel VanSanten will star as Quinn, the latest member of Haley’s(Bethany Joy Gaoletti) family to stir up drama, and Brooke(Sophia Bush) will have Alexis played by Jana Kramer as the new face of her clothing line.   

Bush says she looks forward to what’s in store for her character on the newly revised ‘One Tree Hill’. “It’s really exciting for Brooke this year, with her business [and] her relationship with Julian (Austin Nichols), Brooke and her mother had a beautiful ending to their story last year, and I’m really excited to explore that as well with Daphne [Zuniga]. It’s going to be really good.”
