Sophia Bush and Austin Nichols are getting married ... on TV.

The couple, who are actually dating in real life, will tie the knot on their CW show "One Tree Hill" -- and it looks like one gorgeous affair.

In new photos, posted over at TVLine, Bush looks absolutely stunning in a strapless wedding dress next to the dapper Nichols.

The nuptials for "Brooke" and "Julian" will air next week. Wonder if shooting this episode gave Austin and Sophia any ideas ...
