Mrs Moghalu shared the story in a tweet on Wednesday while also revealing she had her nails done.
She said she learnt to make nails in the United States and returned to set up what she claimed was the first nail studio in Arusha, Tanzania.
“Did my nails today. I used a matte top coat for a change. Incidentally, I am actually a licensed nail technician! Years ago, in Arusha, Tanzania when I found no one to do my nails, I went to the USA and learned. Came back and trained 2 girls and opened the 1st nail studio there,” she said.
It was not immediately clear if the business was still running.
Moghalu and his wife celebrated their 26th wedding anniversary in December 2020.
