The duo – comprising twin brothers Peter and Paul Okoye – fell out a couple of years ago over family feuds, with the band finally splitting up in 2017.
The two, who turned 40 on Thursday, had dominated the Nigerian music scene for years with their music being a sensation in the country and beyond.
They were recently seen embracing each other in a video shared widely on social media.
Pulse Nigeria shared the video on Twitter:
One social media user said on Instagram: “Please let this love and reconciliation last forever. Amen.”
“I’m feeling emotional. As a twin I can’t imagine not being on good terms with my twin sis for long,” another said.
