Looking bright-eyed and bushy-tailed, Sophia Bush was up and at ‘em in New York City on Monday morning (December 6).

The “One Tree Hill” babe was all smiles as she passed by the paparazzi en route to Pix11 Morning News studios for a promotional appearance.

Ms Sophia was joined by her on and off-screen beau, Austin Nichols, with the cute couple explaining their latest project called “Gasoline Rainbows” - which is a music compilation giving 100% of its proceeds to Global Green to help communities affected by the Gulf oil spill.

Sophia and Austin traveled with Global Green to Grand Isle, Louisiana back in June to visit the beaches and see the devastation first-hand, which ended up inspiring them to come up with the idea of the new album now available on iTunes.
