Usher's son wants to be a scientist.
The 'U Got it Bad' hitmaker, 37, has revealed six-year-old Naviyd is keen to carve out a career in the laboratory when he's older because he wants to discover a long-term cure for his seven-year-old brother Usher Raymond V's diabetes.
Speaking to the New York Post newspaper's Page Six column, he said: "I have two sons. Usher Raymond V, we call him Cinco, has Type 1 diabetes."
He added: "My youngest son knows I worry about Cinco and recently told me, 'Do not worry! One day, I'm going to be a scientist and cure this for my brother.' "
Cinco was diagnosed with the lifelong condition last year and the handsome singer has admitted it has been a tough 12 months understanding the condition and adjusting to it.
He explained: "A child that every day has to prick himself [with an insulin needle] and has to be cautious of what he eats and also to carry this disorder around -- that really is the type of bravery that we all aspire to have."
He added: There's been some difficult moments but having dealt with it on a daily basis, I have a great deal of understanding of what people have to deal with."
Meanwhile, the star has certainly had a busy few months as he recently tied the knot in a low-key wedding with his long-time girlfriend Grace Miguel following six years of dating.
A source said previously the pair secretly eloped and got hitched over Labour Day weekend in the US in September.
