Adrien Broner = 30 years old
Bhad Bhabie (aka Danielle Bregoli "Cash me outside, how bout dat") = 16 years old
1:53 PM PT -- Adrien Broner is offering up an explanation ... calling the whole thing an "honest mistake."
"Nobody want to date a kid," Broner told The Shade Room ... "but I fault Instagram for not having people’s age on they profile."
"I thought she was grown the way she out here moving."
Just an honest mistake....nothing to see here
