Zubby Michael took to Instagram to congratulate his "kid sister" on her promotion as a staff of the Federal Road Safety Corps, FRSC.
Sharing a photo of his sister, Cynthia Egwu, in her uniform, the actor asked God to bless her.
He then said that she has "chosen to be useful when most of our girls are desperate for fame and going into mobile prostitution".
His comment did not go down well with many people and he was called out by some followers.
