Angelina Jolie will give Brad Pitt a pendant with microscopic words on it.

Based on Ancient Egyptian amulets, the romantic gift will have the secret love message lasered on so no one can read it without a microscope.

The 35-year-old actress commissioned London-based jeweller Robert Procop to make the piece for Brad, whom she has been dating for six years.

Robert said: "I can't tell you what it says, and you would need a microscope to read it. The technology is quite new. The hidden message is lasered on."

Formerly a chief executive of upmarket jeweller Aspreys, he also revealed that he is going into business with the stunning star, to create a line called 'The Style Of Jolie'.

He told the Daily Mail newspaper: "Angelina has very classic style. These are pieces she wears herself."

Last year, the 'Tourist' actress teamed up with Brad to create a gold and silver collection for Asprey, with all profits donated to the Education Partnership for Children of Conflict, which she co-founded.
