Lady Gaga performs 'Hair' - bald

Has Lady Gaga shaved her head or is she wearing a skull cap?

Opinion is currently divided as to whether Lady G's bald appearance on the Paul O'Grady show was down to a razor or a carefully applied skin tone swimming hat - and we want to know what you think. 

The singer whipped off her green wig to perform a piano rendition of 'Hair' for a live audience and appeared to be as bald as the day she was born (assuming she was born bald).

She recently revealed that her natural hair has started to break off as a result of too many dye jobs, and so it could be that the 'Born The Way' singer took matters into her own hands.
