According to media reports, the slay queen who is known for her porn and nude pictures – was ejected from the military facility even before the 34-year-old grandson of Queen Elizabeth arrived.
Prince Harry was in Zambia from Monday afternoon and met President Lungu.
The Prince was then due to meet World War 1 veterans and widows at Burma Barracks to commemorate 100 years since the end of the war on Tuesday.
As he was being awaited by a small group of carefully selected guests and a handful of accredited journalists in the barracks, a beaming and attractive Iris pitched up donning a white loose fitting dress, centimetres shy from touching knees.
The lady shook hands with a few waiting journalists before making her way to the memorial hall where the war veterans and widows had been staffed to await the Prince.
However, shortly after, Iris was seen being talked to by a uniformed military man before they walked together towards the exit of the barracks.
The military officer returned a few minutes later without Iris – apparently she was not on the guest list.
Prince Harry then arrived about 15 minutes later and proceeded to fulfill his programme with Iris nowhere in sight.
Iris Kaingu made headlines last year after she went totally unclad in order to be painted by an artist.
Ms. Kaingu was also convicted by the Lusaka Magistrate Court in 2002 for making a “porn” video..
