Boxing great Floyd Mayweather, Jr. has become a grandfather at the age of 43.

The fighter’s daughter, Iyanna ‘Yaya’ Mayweather, has welcomed her first child, a son, with rapper YoungBoy Never Broke Again, and she took to Instagram to share the news with fans on Saturday.

Sharing a close-up photo of herself holding the newborn’s foot, the new mom wrote, “From the very moment you arrived, I felt something new inside. I developed a love that was so unconditional. And I promise to give you everything I have.”

Her baby daddy, also known as NBA YoungBoy, has yet to comment publicly on the baby’s birth.

The child is believed to be the seventh kid for the Self Control star, real name Kentrell DeSean Gaulden – he reportedly welcomed his second daughter with his ex, Drea Symone, on America’s Thanksgiving holiday, just five months after another former lover gave birth to his son.
