AMERICA gave Trista Rehn and Ryan Sutter a nice wedding present – millions of viewers for their nationally televised wedding.

The Rehn-Sutter nuptials snared 17.1 million viewers Wednesday (9-11 p.m.), the night’s top-rated show.

The wedding, the third of a three-part prime-time extravaganza, also led ABC to a rare mid-week prime-time victory.

Rehn, the castoff from the very first “Bachelor” series, chose Sutter, a Colorado fireman, over slick Charlie Maher in “The Bachelorette.”
