PHOTOS: Shocking star splits The actress has split with her on-and-off beau of six years, Austin Nichols, 31 -- the third guy she's dated from the just-wrapped TV hit -- a source tells the new issue of Us Weekly (on stands Friday).
PHOTOS: Ugly celebrity breakups Bush broke it off with Nichols (who plays her husband) "because she didn't think he was the one," explains a source.
I thought, 'If I could do this for the rest of my life, I am set.' It was like love at first sight." Bush made her first big screen appearance in the 2002 film National Lampoon's Van Wilder opposite Ryan Reynolds.
In 2003, Bush landed the role of Brooke Davis in the WB television series One Tree Hill.But now Bush has opened up about the romance, admitting she and her beau actually started dating in 2006 - two years before Nichols even started working on the U. She says, "We've been dating off and on for the past four years. We had so many years of history prior to him coming to work on the show, and I think someone taking a job and moving their life across the country to show you how much they care is pretty much the most romantic gesture that a person could make." Bush was briefly married to former "One Tree Hill" star Chad Michael Murray in 2005.It's a wrap for Sophia Bush, in more ways than one."She's moving on."
