Egypt's Antiquities Ministry says it's inviting an Egyptologist behind a theory that the tomb of Queen Nefertiti may be located behind King Tutankhamun's 3,300-year-old tomb in the famed Valley of the Kings.

Wednesday's statement says British-educated expert Nicholas Reeves has been invited to Cairo in September to debate his theory with Egyptian colleagues.

It says there could also be a joint expedition to Luxor, where the 18th Dynasty King Tut's tomb is located.

Reeves argues that Tut, who died suddenly at the age of 19, may have been rushed into an outer chamber of Nefertiti's original tomb. He says high resolution images show Tut's tomb might have two unexplored doorways.

Some archeologists believe the mummy of Nefertiti, fabled for her beauty, has already been found in a different tomb.
