The Warri-born up and coming rap artist beat Bisola, who became the 1st runner up with 18.54 per cent of the vote at the grand finale.
Tboss scored 13.60 per cent to emerge the 2nd runner up; Debie-Rise 8.78 per cent, 3rd runner up while Marvis scored 1.47 per cent.
Efe was given a brand new Kia Sorento SUV and N25 million naira cash prize.
Efe who had never failed to stress that he was real was nominated for eviction in January and March but survived.
The economics graduate had stressed that his humility, simplicity and being real would make him win the hearts of viewers.
His emergence came after Marvis, Debie-Rise and Tboss were evicted during the grand finale.
Efe who was Marvis’ love interest in the house said in spite of the attraction between them, he was careful not to do anything that could jeopardise his stay in the house.
He was Head of House once and had been very active in most games and tasks in the Big Brother House.
He had actively participated in the ONE Campaign song, the video shoot, drama and others.
He had always been delight of the party during the usual Saturday night party in the house.
Efe, during Davido’s visit said if he won the grand prize, he would use it to push his music career to the next level
Earlier in the run-up to his announcement, Bisola, was announced the winner of the One Campaign.
Bisola’s winning the One Campaign appeared to be an anti-climax.
The One campaign will make Bisola represent Nigeria at the United Nations later.
High point of the grand finale was musical performances by Tiwa Savage, Emmy Gee featuring AB Crazy and Tuface Idibia.
