Not that you COULD have missed these sexy photos, but if you couldn't believe what hot Chinese star Zhang Ziyi was doing on the beach with her fiance, neither could our photographer!

Says the snapper, "It was definitely more than just an affectionate pat on the behind -- these two were getting so hot and heavy that if they didn't hit the water, they would have steamed up the entire beach!"

Her manager has released a statement claiming that Ziyi and her fiance, Vivi Nevo, were just "enjoying a normal part of life for the two of them," and that these photos are an invasion of privacy.

Last time I checked, there's nothing "normal" or "private" about extreme PDA in public!
