Tyler Hilton is heading back to One Tree Hill.

The singer/songwriter/actor teased this return on Twitter this week, writing that he's "doing something soooo exciting," and now Zap2It confirms: Hilton will reprise the role of Chris Keller for at least an episode or two.

Keller has not been seen on the show since season four. That's a decade in OTH time! Look for him to get involved with Haley, giving her a hand with Red Bedroom Records with Peyton still out of the picture.

One Tree Hill will return with its final season some time in January.

UPDATE: TV Line now reports that Hilton has been made a series regular! He'll return on the final season premiere.
