RUMOUR OR TRUE? i hear that James Lafferty and Sophia Bush are dating in real life!?
I was a extra on the show Monday and I believe it more that they could be together. She was there all day before she was supposed to be filming, just there taking pics of just him. And when they did talk they got close and made eye contacts every once in awhile. But just wanted to share this, guess time will tell!!!
