Nick Carter's romantic proposal was almost ruined by his broken boat, which kept threatening to quit on him as he and his girlfriend headed for an island off the coast of Florida.
The Backstreet Boys star had mapped out a beautiful trip, during which he was planning to ask Lauren Kitt to be his wife, but he forgot to make sure his old boat was in good working order.
He tells Access Hollywood Live, "I took her down to the Florida Keys, where I lived for a little bit and I have a boat down there... and I took her out to an island... and I proposed to her on there. I wanted it to be special.
"On the way out there the boat kept breaking down 'cos I hadn't used it in, like, eight years... She was like, 'Why is he bringing me out here?' And the engine kept stalling. It was memorable for sure.
"We got close to having to call the coastguard."
Nick Carter and his fitness trainer wife-to-be became engaged in February (13). They are hoping to wed in early 2014.
