The happy parents who already have a son together shared the happy news via Instagram.
The "Obianuju" crooner shared a photo of their newborn princess in a post he captioned, "God has just blessed me with everything and now she is the cutest babe girl ………
"God alone is the doer and him alone be glorified ….. to my worlds best wife thank you so much for giving birth to what I wished myself.
"Michelle Jewel Mighty is Born #MJMIGHTY #bestdad #proudfather #duncanmighty #celebrityengineer #yungwealthrecords."
Duncan Mighty has had a lot going for him of late, which definitely explains his excitement with the latest addition.
In the last year, the singer acquired a new home, has flaunted a lot of cash despite the difficult economy, and now has a pretty little girl.
Duncan and Vivien tied the knot in July 2015 after dating for two years.
Big congrats to them.
