London, Jan 31 : David Hasselhoff may have already popped the question twice to girlfriend Hayley Roberts, but her snubs didn't put David Hasselhoff off trying his luck again - this time on top of the Sydney Harbour Bridge.

After being snubbed twice earlier, Roberts might have said yes, judging by the picture posted on the `Baywatch' star's Twitter page.

Hasselhoff, who has been married twice in the past, was seen on bended knee as he asked Roberts, 32, to marry him, before kissing the Welsh beauty in a passionate embrace.

The 59-year-old actor captioned his second picture with the words: "What do you think she said?!" the Daily Mail reported.

And while Roberts didn't confirm the news on her Twitter page, she did post a crypitc: ":-)))))) xxxxxxxxxxxx"

A representative for Hasselhoff has yet to confirm the news. (ANI)
