It was one of our favourite American TV series, which aired from 2003 to 2012, and thankfully for fans the cast reunite every now and again at conventions.
James Lafferty, who played one of the lead characters Nathan Scott, was at Eyecon's annual One Tree Hill themed convention in Wilmington, North Carolina, and so was his on-screen son!
Jackson Brundage played Nathan and Hayley's eldest child Jamie and he was a total cutie on screen.
Now, he still has the same baby face, but he's just a lot more grown up!
Tons of other cast members were there too, including Antwon Tanner (who played Skills Taylor), Lee Norris (who played Mouth) and star of the show Chad Michael Murray, who played Lucas.
For anyone who doesn't know what OTH was about, the drama series was set in the fictional town of Tree Hill, North Carolina, and initially followed half-brothers, Lucas and Nathan Scott, who were competing for positions on their school's basketball team.
