BEIJING, Aug. 28 -- Madonna is furious that her explicit love letters may be made public.

    The "Give It 2 Me" singer has reportedly instructed her lawyers to stop the organizers of new exhibition "Simply Madonna: Materials of the Girl" from displaying the racy notes.

    Madonna sent the 17 letters - which include photographs - to her then-boyfriend James Albright in the 90s and signed some of them Spanky, said to be a reference to her fondness of being spanked during sex, while others include a lipstick kiss.

    A source said: "Who would want private sentiments to someone they loved revealed? Lawyers sent a warning. She hopes it will work."

    The show will open in East London next February, and will include some of the most iconic stage outfits she has worn during her 25-year career.

    Among the 300 items going on show are the pink dress the singer wore in the "Material Girl" video, and the evening dress from the 1996 film 'Evita."

    A black bustier she modeled in her "Open Your Heart" video and the wedding dress she wore during her "Like a Virgin" tour will also be displayed.

    Exhibition Curator Ted Owen said: "This is an unprecedented collection of Madonna memorabilia, that represents every stage of her glittering career.

    "These are museum-quality pieces - but they will be presented in keeping with the glamour and sense of theatre that the queen of pop has made her trademark - and Madonna fans should be very excited indeed."

    Madonna kicked off her 50-date "Sticky and Sweet" world tour in Cardiff, Wales, on Saturday.
