Garth Brooks and Trisha Yearwood are kicking the holiday spirit up a notch with a new social media campaign.

The superstar couple are inviting fans to post photos of themselves wearing their ugliest Christmas sweater using the hashtag  #UglyXmasSweater for 12 days in a row. At the end of the series, Brooks and Yearwood will select their favorite sweaters to be featured in a video compilation across social media.

Fans can access a custom filter when they visit the campaign's official site. In a Facebook post announcing the campaign, Brooks says, "There's really nothing better than a beautiful girl in an #UglyXmasSweater," alongside the humorous photo of he and his wife donning their own ugly sweaters. 

The campaign is inspired by a track by the same name off their new Christmas album, Christmas Together, which debuted at No. 1 on Billboard’s Top Country Albums chart in November. It is their first duets album, and features many festive holiday tunes including "Feliz Navidad," "The Man With the Bag," "Hard Candy Christmas" and more.

This isn't the first time the star couple have used social media to bring fans together. They recently launched the #WhatImThankfulFor campaign in honor of the holiday season, receiving more than 60,000 photos of fans sharing what they're most thankful for. The new Christmas album also features a duet with James Taylor on the song "What I'm Thankful For."

The power couple have had a busy year to say the least. In addition to the release of their Christmas album, the two are coming up on the third year of their world tour. Brooks is also celebrating the release of his solo album, Gunslinger, a career-spanning box set, Garth Brooks: The Ultimate Collection and big win for Entertainer of the Year at the 2016 CMA Awards.
