Justin Timberlake Crashes Wedding

Justin Timberlake was part of a diabolical plot by the father of a bride to create a wedding for the books.

The scene is upstate New Hampshire. Chelsey Gaudet and Ryan Parks were just starting a pre-wedding photo session when Chelsey's dad happened to spot one of the most famous people in all of entertainment ... JT.

Justin grants dad his big wish and mugs with the bride and groom.
