Youth minister Florence Nakiwala told the BBC that the country’s labour laws state that no-one under 18 should work.
In an interview on Uganda’s NBS channel, she also warned that if the seven-year-old rapper, Fresh Kid disobeyed the law he could face juvenile prison.
Ms Nakiwala expressed concern that Fresh Kid, whose real name is Patrick Ssenyonjo, missed school since he was always busy working when other children his age were studying.
What Fresh Kid manager replied
His manager, Francis Kamoga told the BBC that the rapper only performs on Saturdays and Sundays and has only had two shows, one music video and three songs since the start of the year.
He added that he is not working and does not get paid.
“I discovered him in a rural village miming some songs, brought him to the city and started paying his school fees” he said.
His latest music video
The star addresses critics in his latest song Banteka where he raps in a mix of Luganda and slang about people gossiping about him not going to school:
"They underrate me because of my age, I hear what you are gossiping about: asking 'will he study?"
"Losers are weeping, calling out to their mothers, If you are afraid of me, get me cash. I'm the judge, I do not discriminate. Even if you are from the stone age, I will floor you."
