Reacting to Namakula's message, fellow songstress Maureen Nantume posted: "❤️❤️"
The doctor and the songstress share a daughter named Aaliyah Ssebunya, born on November 7, 2021.
The daughter she shares with Eddy Kenzo, Aamal Musuuza, also lives with them.
The two have always praised each other.
While introducing him to her family, Rema Namakula said: "Honey, I appreciate you so much for accepting to pick me from many... I, Rema Namakula, used to pray and fast, asking God to also give me mine.
"God is not corrupt. God doesn't take a bribe. And because of that, my friend, my father, our daddy, I have a gift, I want to tie you. I'm ready. Sit, relax, enjoy the love ride."
In 2023, she said of their marriage: "Please, can Mr. Sebunya be chucked? That baby being chucked? I'm in marriage for the long haul, those are your issues. That one can't be chucked, please."
That same year, Hamza Sebunya said he found peace in marrying Rema Namakula.
"I take this opportunity to thank my wife and also thank God for giving every man here a woman that gives him peace," he said.
"Everyone should be given a friend because for me she was my missing peace, and I say this proudly... I ask God to increase the love between us. I asked for peace, and God gave it to me through her. I thank God and ask him to keep us together."
Hamza Sebunya recently revealed that he and Rema Namakula are in a healthy marriage.
