Onyeka Onwenu opens up on ‘secret marriage, sleeping with Obasanjo’.. Veteran singer, Onyeka Onwenu has finally clarified rumours that she had a secret marriage with former President of Nigeria, Olusegun Obasanjo. Onwenu in an interview with popular media personality, Chude Jideonwo, said the accusations that she slept with Obasanjo and had a secret marriage with the former President is false. She also revealed she was accused while growing up of sleeping with many big men in Nigeria. The veteran singer said: “I was accused of sleeping with Sunny Ade, Fela and Obasanjo. “They even went to the extent of saying I got married to Obasanjo secretly. If he approached me to marry him, why would I keep it a secret? We would have made it public so that was funny.” She added that her marriage to her ex-husband would have almost killed her if not for her brother who saved her.
