Oh no! It looks like Sophia Bush has split with her ‘One Tree Hill‘ co-star Austin Nichols, reports Us Weekly.
The couple who play a married duo on the hit CW show have been on-and-off for six years and according to a source the reason behind the split was because Bush doesn’t think he’s the one. “She’s moving on,” says the source.
Sophia was previously married to Chad Michael Murray back in 2005.
‘One Tree Hill’ is in its last season and series finale will air on April 4th.
