The parents of recently admitted bisexual Jeremy Lambert said they completely half-understand their 19-year-old son's lifestyle choice and are 50 percent behind him no matter what happens, sources reported Monday. 'I can honestly say that I partially accept my son for the special person he is,' said Kenneth Lambert, 44, adding that nothing would ever change that. 'I know it must have been tough for him to come out and tell us part of what he had to say. He should be very proud of half of himself.'While Lambert's mother Lisa has remained silent on the matter, many believe that, unlike her husband, she is almost three-quarters accepting of her son.
