Spencer William Pratt (born August 14, 1983) and Heidi Blair Pratt (born Heidi Blair Montag; September 15, 1986) called off their divorce on September 2010. Spencer William Pratt should changed his name is name to Spencer will.I.Am. Prat (understood that? Because "I am a prat," right?).
I am not so sure....his family is highly invisible so either it is an agreement with his family to not be apart of his life style, or they see him as an embarrassment and do not want to be associated with his highly publicized life style.
