Actress Sophia Bush has split from her One Tree Hill co-star and on-screen husband Austin Nichols.
She's moving on... because she didn't think he was The One
The couple recently ended its onoff relationship after six years of dating.
A source tells UsMagazine.com, "She's moving on... because she didn't think he was The One".
Bush was previously married to fellow co-star Chad Michael Murray in 2005, while she also romanced another castmate, actor James Lafferty.
The Day After Tomorrow's Nichols broke off his engagement to artist Claire Oswalt in 2004 following a seven-year courtship.
