Onyeka Onwenu mourned: Tributes paid to Nigeria's 'One Love ...

Kelex Ofoedu, official photographer to Abia state governor Alex Otti, posted pictures, external of Onwenu performing at the birthday party, adding: "Who knew she’d be gone after I took these images of her last night.

"She sang extremely well, was humorous, and made everyone very happy with her performance."

According to local media reports, Onwenu died at Reddington Hospital in the Lekki area of Lagos.

In his tribute to Onwenu, President Tinubu called her a "versatile and extremely gifted artiste" who brought joy and laughter to many.

Fellow musician Charly Boy said Onwenu's "impact transcended the entertainment industry".

"RIP Ma Onyeka Onwenu," award-winning musical duo P-Square posted on social media platform X.

"The nation has lost a timeless legend and great artist," popular lawmaker Shehu Sani said. "Her melodies will forever resonate in our souls."

Born in 1952, Onwenu mostly released soul and gospel records.

She also acted in Nigerian films, winning several awards for her contributions to music and film.

Onwenu took up other roles outside of the entertainment industry, including broadcasting, activism and politics.

She used to be a member of the main opposition Peoples Democratic Party (PDP) and twice stood unsuccessfully for a local government seat.

During last year's general election, she endorsed the rival Labour Party, which came third.

The party's Lagos state chapter said it was “deeply saddened" by the "iconic" singer's passing.

“This is unbelievable! Onyeka Onwenu was a celebrated Nigerian singer, songwriter, actress, journalist, and politician who virtually every Nigerian is proudly fond of,” its statement said.
