Floyd Mayweather & Jen Welter -- Hand-in-Hand Before Fight (PHOTO)

Jen Welter is officially pissing off a lot of women, by posting this pic locking hands with Floyd Mayweather.

The first NFL female coach said, “What an amazingly warm welcome … honored to support & be accepted as family.”  Welter was skewered by many for accepting an invite to join Mayweather in Vegas for his fight against Andre Berto tonight …  given his abusive history with women.

Jen has said Floyd’s been hammered too hard … “He has a tough past.  His childhood was not pretty.”
