Christie Brinkley starred in this week's holiday-themed "Parks and Recreation" special episode as Jerry Gergich's heretofore-unseen wife Gayle, according to Yahoo!

Viewers already met Jerry's (played by Jim O'Heir) daughter Millicent, and the other show's characters stay are speechless when they find out at a holiday party that the parks department employee is married to the beautiful Brinkley, though she does not play a model in the show.

Thursday's episode, the ninth one for season five, is titled "Rob & Diane." TVEquals.com provided an episode synopsis for fans: "Ron (Nick Offerman), Diane (guest star Lucy Lawless), and Leslie (Amy Poehler) attend a wood working awards dinner, after one of Ron's handcrafted chairs is nominated, but the happy occasion is threatened by the arrival of Tammy II (guest star Megan Mullally). Meanwhile, Jerry hosts a holiday party at his home...and some of his friends are shocked to find they were not invited."

"Parks" is not the first time Brinkley has tried acting. The Sports Illustrated model had a guest appearance on an episode of "Ugly Betty," and also appeared in the films "Jack And Jill" and "Vegas Vacation," according to The Huffington Post.

"Parks and Recreations" airs on NBC at 9:30 p.m. Eastern Time. The series first aired in 2009 and stars Amy Poehler, Rashida Jones, Rob Lowe and Aziz Ansari. Set in a town in Indiana, the show follows local public officials and their humorous antics. Poehler was nominated at this year's Golden Globes for Best Performance by an Actress in a Television Series - Comedy or Musical. Though "Parks" has been nominated for a slew for Primetime Emmy Awards since 2010 for its acting, directing and even writing, it has yet to receive an award.
