Waterworld star Costner sees boat sink

Hollywood actor Kevin Costner fought to hide his blushes when he took his fiancee Christine Baumgartner for a romantic boat trip in a vessel that started to sink.

The couple were spending time at Costner's Aspen, Colorado, ranch before their planned wedding this weekend and the star attempted to impress his bride-to-be by building her a boat and packing a champagne picnic.

But a source claimed: "Christine began using her champagne flute to bail out water while Kevin rowed furiously for land."
