David Hasselhoff Proposes Atop Sydney Harbour Bridge

"Baywatch" and "Knight Rider" star David Hasselhoff on Tuesday proposed to girlfriend Hayley Roberts, 28 years his junior, on top of the Sydney Harbor Bridge.

Hasselhoff, 59, posted the news on his Twitter account, but left his followers guessing over how Roberts, a Welsh factory worker, replied.

"Tried it again on top of the Sydney Harbor Bridge. What do you think she said?," he tweeted, alongside a picture of him on one knee and another of the pair embracing during a climb to the top of the Sydney icon.

According to reports, the twice-married father-of-two has asked the 31-year-old to marry him before, once in his "Britain's Got Talent" dressing room and again atop a mountain in Cape Town, South Africa.

Hasselhoff is in Australia filming reality television show "Celebrity Apprentice Australia".
