The split had come after photos of the singer and a lady kissing surfaced online.
But in a now-viral video, the pair were being interviewed on a live TV when Grand P went on one of his knees to apologise and popped the question.
“You are my life, I have changed, whatever happened is the past, I won’t repeat it, it won’t happen anymore, believe,” he said in French.
In the video clip, the curvy Ivorian socialite, who appeared stunned by his request, hesitated before eventually accepting the proposal amid cheers.
Yao also took to her Instagram page to share the clip.
In a terse post accompanying the video, she reflected on Grand P’s gesture, saying “I have a very big decision to make”.
She also talked about her struggles trusting the singer again after what transpired between them in the past.
“My ex baby’s marriage proposal was hot I have a very big decision to make…Can I still trust big P?” she wrote.
