Country singer and former Survivor contestant Whitney Duncan is engaged – and this time it’s not a secret.
Duncan, 28, was secretly married when she met and fell for Tollefson, 27, on Survivor: South Pacific in the summer of 2011 but now the tribemates are headed down the aisle.
“He did good,” Duncan wrote on Facebook along with a photo of her sparkling engagement ring of interlocking circles in a complex pattern.
