Last week, upcoming singer Lastborn, in an interview with NTV Uganda, accused Grenade of having an affair with his wife.
He alleged that the "Nkuloga" hitmaker has been sending his wife endless romantic messages and always keeping her phone busy.
However, Grenade has denied any relationship with the purported woman. The singer explained that the upcoming artist is just using his name to gain fame and attention.
"I am fully focused on my music, and I have a woman I love and have loved for years. There is no reason why I would leave her to pursue other people's wives. That kid is looking for relevance," he said in an interview with a local television station.
Grenade is popularly known for dating city cougars and sugar mummies.
