The wedding was held at the National Christian Centre, Abuja.
Obasanjo had in his book titled My Watch, come hard on Jonathan's style of leadership.
The duo had not met since the public presentation of the book.
The former president had recently flayed the incumbent for allegedly mis-using the foreign reserve.
Obasanjo's comment elicited reactions from Jonathan's loyalists who rose in support of their principal.
However, Obasanjo stormed venue of the wedding with Dr. Andy Uba, as well as a retinue of his before the service.
The former president's arrival was greeted with deafening ovation from guests.
