Here they are at the peak of their love story on-screen: Sadly, just five months into married life, our hopes and dreams for the real-life Brooke and Lucas fell apart as their marriage crumbled following reports that Chad had cheated on his wife with Paris Hilton. Following her turbulent break-up with Chad, Sophia didn't beat around the bush and began something with co-star James Lafferty.

In May 2008, they officially became an item before ending it exactly a year later. The actress dated her third man from the series in the shape of Austin Nichols.
