Songwriter Kyle Jacobs wrote and recorded a song for her, called "Say I Do," and used their private wedding footage for the music video. Fans can buy it on iTunes for $1.99.
Jacobs, 37, tells The Associated Press the video shows "two people madly in love." It was shot on 8 millimeter film by a Nashville videographer who accompanied them to the Caribbean island of Antigua, where they eloped on New Year's Day.
The video captures their arrival, intimate moments walking on the beach and ultimately the wedding ceremony that took place on a sandbar stretching 200 feet into the ocean. Pickler, 24, wore her flowing Badgley Mischka gown into the ankle-deep water where Jacobs was waiting for her. At one point, she wipes a tear from his face and they kiss.

"It was such a beautiful, spiritual, godly moment," said Jacobs. "It felt like we were baptized out in that beautiful, crystal-blue water."
The couple ditched their plans for a big wedding after an ah-ha moment when they realized the guest list looked more like a typical music industry event.
"It felt like what we were planning was work," he said.
Writing a love song for his wife-to-be, on the other hand, came easy to Jacobs. He has penned an estimated 800 songs since signing a publishing deal with Curb Records six years ago, including the No. 1 Garth Brooks hit "More Than A Memory." He said Pickler has inspired too many to count.
Jacobs credits her for giving him the encouragement and confidence he needed to give singing a shot. "Say I Do" is his first release as an artist on iTunes.
So far, he said, the reaction from family and friends has been overwhelmingly positive.
"It almost feels like God's stamp of approval, just saying, 'Hey, listen to your wife and try this out,"' he said.
Pickler finished in the top six on "American Idol" in 2005. Her songs include the top 10 hit she co-wrote with Taylor Swift, "Best Days of Your Life," as well as "Red High Heels," "Don't You Know You're Beautiful," and her most recent single, "Makin' Me Fall in Love Again."
In addition to the Garth Brooks song, Jacobs' songwriting credits include Tim McGraw's "Still," Kimberley Locke's top 10 pop hit "8th World Wonder," as well as cuts by Randy Travis, Trace Adkins, Craig Morgan and a track on Kelly Clarkson's upcoming album called "The Sun Will Rise."
