Chad Michael Murray and Sophia Bush can now legally move on with their lives, and so can "One Tree Hill" fans.

The divorce between the CW co-stars is now final, reports People.

According to court documents, both sides waived spousal support. They have no children together.

Bush, 24, and Murray, 25, began their romance on the set of their first season of the WB (now CW) drama "One Tree Hill," on which Bush plays cheerleader Brooke Davis, and Murray plays the brooding Lucas Scott. They wed in a seaside ceremony at the Casa del Mar Hotel in Santa Monica, Calif., in April 2005, but split in September.

At the time, Bush had petitioned to annul the five-month marriage on the grounds of "fraud," which is legally difficult to prove in California. With such a brief marriage, there's no telling what fraud could mean, although popular theories are infidelity or closeted homosexuality. One of Bush's friends hinted at the former: "Sophia went into the marriage believing in the sanctity of marriage, and Chad simply did not share that vision."

Murray is currently engaged to "One Tree Hill" extra Kenzie Dalton, who was only 17 when she started dating the actor. Dalton, who appears as a Ravens cheerleader on the show, was the runner-up in the Miss North Carolina Teen USA pageant in 2005.

Murray has also appeared on "Gilmore Girls" and "Dawson's Creek." His big-screen credits include "Freaky Friday," "A Cinderella Story," "House of Wax" and "Home of the Brave," currently in theaters.

On the big screen, Bush has appeared in "Van Wilder," "Supercross," "Stay Alive" and "John Tucker Must Die." She next stars in the remake of "The Hitcher," which opens nationwide on Friday, Jan. 19.
