ABC is to air a miniseries chronicling the marriage of Bachelorette star Trista Rehn to the man she eventually picked, the net has announced.

Trista has yet to set a date for her wedding with former firefighter Ryan Sutter, although ABC has already decided the date it will be shown on TV.

Trista and Ryan's Wedding will premiere on the last night of November Sweeps, Wednesday 26, at 9pm, continuing on December 3 and concluding December 10 with a two-hour finale.

According to reports, the pair will be paid around $1 million for agreeing to have their wedding televised, but have had to hand over planning of the event to the show's producers.

Rehn and Sutter filmed their bachelor and bachelorette parties last weekend on the Caribbean island of St. Martin.
