According to well-placed sources, First Lady Margaret Kenyatta was also spotted at the high-end hospital.
However, the gender of Ngina’s newborn baby is yet to be established.
The President’s daughter has been missing in public for many months, leading to speculations on her whereabouts but it’s now emerging that she was nursing pregnancy.
Ngina is rumoured to have sired the baby with her fiancé Sam Mwai Junior.
Junior is the son of tycoon Sam Mwai, a famous sports consultant and manager of Karen Country Club.
