Eliasu Zakari and Justina Nhyiraba Gyasiwaa both admitted that they slept with each other only once.
Eliasu Zakari also noted that he has been leaving with Bishop Obinim for about eight years.
The girl disclosed that she came and had been with Obinim for about four years.
A video of the two teenagers which went viral showed Bishop Obinim whipping the two in the full glare of his congregation and questioned why the jobless man got the girl pregnant.
The disturbing video has provoked widespread criticism of the controversial preacher leading to his arrest by Domestic Violence and Victim Support Unit (DOVVSU).
