See MR White I think all RS was told was slap girl & out of that he got fooled like 90% of the public as it being Chantal as she was the most notable. If you go back & look Em was always hitting Brad but not in the face. Last week we even saw Chantal slap Brad the way Emily has done all the long.
RS just jumped the gun on who slap girl really is & never got an actual name. No one was lying everyone jumped to conclusion.
