Hilarie Burton, who played Peyton Sawyer on One Tree Hill, shared a ton of pics from her reunion with her fellow castmates on Feb. 22. "I got a job when I was 20 years old that gave me some of the most important relationships and experiences of my life. I didn’t take nearly enough pictures this weekend and didn’t get photo evidence of everyone, but I love @raenia23 at @fwbcharityevents for bringing us all together," Burton wrote of the event, where she snapped shots with her former co-stars like Chad Michael Murray, James Lafferty, Antwon Tanner, Robert Buckley and Jana Kramer. "Thick and thin, our shared history has been a cornerstone in my life. Love you guys. Xxx." One Tree Hill ran on The WB and The CW for nine seasons from 2003-2012, though Burton and Murray did not take part in the last season. The cast regularly reunites, often at yearly fan conventions that have also included OTH star Sophia Bush, and many have acted together in movies since the series wrapped.
