EXCLUSIVE: Kellie Pickler Is Pretty in Hot Pink for Surprise Vow Renewal

Pickler and Kyle Jacobs say 'I Do' again after eloping in 2011.

Kellie Pickler is headed down the aisle... again!

The 29-year-old singer plots a surprise vow renewal ceremony with her hubby, Kyle Jacobs, on Thursday's two-part season finale of I Love Kellie Pickler, airing at 10 p.m. on CMT. Only ET has an exclusive first-look at the big surprise in the player above!

Forget wedding whites -- Pickler looks stunning in a form-fitting, bright pink mini-dress for the sunset ceremony, while Jacobs opts for a classic beachy-blue button-up and khakis. Stealing a moment together before joining their friends by the water, Jacobs gifts Pickler with a beautiful new bauble.

"You look so pretty," he gushes. "I just wanted something that you could look at that you remember this day. This is a moonstone."

The couple then hits the sand at Rosemary Beach, Florida, with their nearest and dearest pals to indulge in a glass of champagne before revealing the big surprise.

"This is the exact spot where Kellie and I got engaged," Jacobs explains. "Y'all know we eloped, so we were not blessed having our friends with us. So we decided we kinda want to do something special today and renew our vows."

Cue the waterworks!

ET was with Pickler and Jacobs in November, just before I Love Kellie Pickler debuted.

"It's focusing on our love, how much we love each other and how much we love to laugh," Pickler said of the series. "It's kind of like we have a summer scrapbook."

The couple met through mutual friends at a bar in Nashville in 2008. "[We] just kinda locked eyes from across the room and the next thing you know, the next day we were writing songs together," Pickler told ET.

On New Year's Day, Pickler and Jacobs celebrated their fifth wedding anniversary.

"We put each other first and if ever work or people or things become a divider, then we let it go," the singer said of their marriage. "Because we have to protect our sanctuary, which is our marriage. That's No. 1 and everything else can fall into place."
