There are two members in the hip hop/rap duo who call themselves New Boyz. Their real names are Earl Benjamin and Dominic Thomas. They also go by the names Ben J and Legacy. There are no reports of the two giving their phone numbers out to fans, most likely due to privacy. http://en.wikipedia.org/wiki/New_Boyz
There are lots of claims as to what New Boyz number is. None of them have been proven to be his true phone number. Many famous performing artist do not make their personal contact information available to the general public.
