Mr Dino Melaye, a senator, has been criticised for his appearance in a music video depicting his lavish lifestyle.
The song Dino, named after Dino Melaye, features lyrics like "100 cars in the parking lot like I'm Dino".
The video shows rapper Kach pretending to eat dollar bills, displaying expensive cars, a mansion, jewellery and shoes.
Melaye represents Kogi West constituency in Kogi state, where many local civil servants are owed months of back-pay.
And many people took to social media to criticise him:
In the video, Mr Melaye, 43, is seen stepping out of a car, wearing a T-shirt labelled Legend.
The senator is well known for his love of luxury cars, champagne and designer clothes, as his Instagram account shows.
Other lyrics in the song include: "Popping bottles in the club is nothing like I'm Dino" and "Dino Melaiye k'oshi mi o raye", meaning "Get out, I don't have time for this," followed by the chorus "Dino, Dino, Dino".
Kach, son of Nigeria's petroleum minister Ibe Kachikwu, has come to the defence of the senator, saying he has done nothing wrong.
"He just did the video to support me," he told BBC Pidgin. "He's not representing the nation in my video."
Dino Melaye at a glance:
■ Member of the ruling party, APC
■ Published a book titled Antidotes for Corruption
■ Constituents petitioned electoral commission in June to remove him, case pending
■ Alleged to have threatened to beat and rape a fellow senator Remi Tinubu, an allegation he denied
■ Pelted with stones at his home state during public celebration
In the video, Mr Melaye also does his signature dance routine of pulling down his eye-lids and staring at the camera in defiance of his critics.
Last year the senator released a video of himself dancing and singing what is now known as the "ajeku iya song"- a Yoruba proverb which states that if you confront someone bigger than you, you are bound to be badly beaten up.
