<<Wow! Sneaky sneaky Sophia Bush!

It's no secret that the One Tree Hill actress is dating her SEKSI co-star, Austin Nichols, but we were shocked to hear that the two of them have been secretly together for YEARS! And he took the job on the CW soap to be closer to her!

Holy shiz!

She reveals: "We've been dating off and on for the past four years. I was pretty terrified. 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."

Truth! But we're still pretty surprised - seeing how her marriage to former co-star Chad Michael Murray ended!

We wish them the best of luck, though! That show has a year left in it - MAX, so they won't have to act together for too long if they split!

Thoughts?? >>
