Nashville country singer Whitney Duncan may be set to star on 'Survivor: South Pacific' this fall, but that doesn't mean she has forgotten about her cousin Holly Bobo, who is still missing since being kidnapped from her home in April. In a new promo for the show, Duncan sports pink bracelets that read "Hope for Holly" and "Bring Holly Home" in honor of her cousin.

Duncan wrote a blog post on August 22 to make the official announcement that she's headed for 'Survivor,' and in her update, she made sure to call attention to the pink bracelets. "Only for her will I wear pink! (I hate pink)," she says of Bobo. "No new news on Holly right now. Please just keep praying for my family to be strong & that we will have her back with us again soon. It's been over 4 months now, but we have to keep the faith."

Bobo was last seen by her brother on the morning of April 13. Unfortunately, though she was dragged into the woods by a man on foot, very little information has been found regarding her disappearance.

Duncan will keep Holly Bobo in her thoughts when she takes on the 23rd season of 'Survivor,' and the former 'Nashville Star' contestant assures that she's ready to jump in head first. "I'm stoked, I mean, I've never done anything like this. This is completely out of my comfort zone," Duncan says in the show promo. She assures, "People may think I'm Barbie, but I'm actually closer to kick a--- Barbie."

Additionally, Duncan will release a new EP this fall, and her song 'So Sorry Mama' is lined up for the 'Footloose' remake movie soundtrack. Of that accomplishment, she says, "Never been on a soundtrack before, so that's pretty cool!"

'Survivor: South Pacific' starts on September 14 on CBS.
