Character names: Lucas Scott & Brooke Davis
Years dated in real life: 2 and a half years

While their characters were having a tumultuous on-again-off-again relationship for nearly nine years on the CW's basketball drama One Tree Hill, Sophia Bush and Chad Michael Murray were having a real life love affair of their own. The young celebs dated for over two years before getting married in 2005.

Sadly, neither their real life relationship nor that of their characters lasted. After just five short months, the marriage was annulled. In the wake of the marriage's collapse, Bush was quoted as saying, "It devastates me now that I have been reduced to a Hollywood statistic—another joke marriage. I never expected to be married more than once...because I knew what I was getting into and will always believe in love."
