Sophia Bush & Austin Nichols Race to Erase MS

Sophia Bush takes her One Tree Hill co-star (and real-life boyfriend) Austin Nichols to help fight multiple sclerosis at the 2010 Race to Erase MS at the Hyatt Regency Century Plaza on Friday (May 7) in Los Angeles.

Earlier in the day, the 27-year-old actress attended the P.S. Arts Presents The Bag Lunch event also in L.A.

Last month, Sophia shot the comedy pilot Southern Discomfort for ABC. Prior to that, she and Gossip Girl‘s Ed Westwick were in Germany shooting their new movie, Chalet Girl.

FYI: At the “Race,” Sophia wore Monique Lhuillier and Austin wore John Varvatos.
