Country singer Whitney Duncan has tied the knot with boyfriend Keith Tollefson. The Skinny Dippin' singer and her beau were married in Humboldt, Tennessee recently, and Duncan took to her Facebook.com account on Tuesday (29Jul14) to share the exciting news with her followers. Posting a photo of the happy moment she and Tollefson exchanged vows on the patio of a classic antebellum mansion, she wrote, "Keith and I are hitched! Southern wedding at Twin Oaks in TN (Tennessee) could not have been more perfect!" The couple first met while competing on U.S. reality series Survivor: South Pacific in 2011, when Duncan was married to another country crooner, Donny Fallgatter. Duncan finalised her divorce in late 2011, and Tollefson proposed to her on Valentine's Day last year (14Feb13).
