In the best reunion news we've seen all year, the cast of one of our favorite shows has just reunited and documented the whole thing on Instagram. The cast of One Tree Hill were all smiles as they joined each other a few years after the show went off the air. Sophia Bush took to her Instagram to post pictures with former co-stars Hilarie Burton, Bethany Joy Lenz and James Lafferty at a convention that took place over the weekend.

The convention is set to hit Milan and London as well with other cast members, including Antwon Tanner, Torrey DeVitto, Robert Buckley, Shantel VanSanten, Kate Voegele and Stephen Colletii set to attend.

Chad Michael Murray was unable to make it to the event, as he's busy working on his new TV series Agent Carter. He did extend his apologies on Twitter, though, writing, "Sorry I can't make it 2 Paris, Milan & London Guys. Heavy into shooting @AgentCarterTV. I'll try 2 make out sometimes soon. Have a great time."

The series ran from 2003-12. While lots of fans have been petitioning for a reunion series, it looks like this is the closest we're going to get ... for now.
