Lisa Marie Presley dressed up like a geisha girl to tie the knot with husband #4 in a top-secret Japanese ceremony — after sources say she signed a pre-nup to protect her $700 million fortune.

Although Elvis' daughter went to great lengths to keep the nuptials under a veil of mystery, The National Enquirer can reveal exclusive details of the lavishly exotic $250,000 affair. And we can disclose the real reason why she was eager to walk down the aisle — she wants a baby right away!
