Hasselhoff determined to walk Hayley up the aisle

David Hasselhoff has vowed to keep proposing to Hayley Roberts until she says "yes".

The 'Britain's Got Talent' star has already popped the question to the 32-year-old Welsh beauty four times, despite only dating for eight months, but David – who posted details of his previous attempts to persuade Hayley to marry him on twitter - says he is already planning his next proposal.
