The stalker, Grzegorz Matlok has admitted to the prosecutor that he has an intimate relationship with her.
The 29-year-old appeared in court in Westminster and prosecutors claimed he had arrived in Britain from his native Poland hours before the alleged break-in.
According to prosecutor Punal Chopra, "Matlok, as he explained in his interview, has initially rung the doorbell, it has not been answered, so he climbed onto the balcony using a rope he brought with him."
"He entered bedrooms and bedclothes have been disturbed, particularly the bed belonging to the artist. He explained to police he had travelled from Poland with the specific intention of meeting the artist known as Madonna who he believes he is in an intimate relationship with."
Matlok was remanded in custody while psychiatric reports are prepared.
