The latest testimony in Barry Bonds' perjury trial comes from Kimberly Bell, the homerun champ's girlfriend from 1994-2003 and someone who surely has an intimate knowledge of the man's physique. According to Bay City News, when asked about Barry's steroid use, Bell told the jury that he flat-out admitted to taking steroids sometime around 1999 or 2000. What's more, she also noticed her then-boyfriend showing notorious side effects of human growth hormone - namely, "acne and shrinkage of the testicles." While being questioned by the prosecution, Bell also described Bonds as being "increasingly aggressive, irritable, agitated" around that time, but maybe he was just feeling grumpy and self-conscious about his girlfriend scrutinizing his withering manhood.
