Bonds' ex-mistress testifies

SAN FRANCISCO - When Barry Bonds' ex-girlfriend walked into a San Francisco courtroom on Monday to testify against the famed baseball player, it was the first time the two had seen each other in eight years.

Bonds, in a blue shirt and dark blue tie, looked down as Kimberly Bell strode to the stand and was sworn in.

The former Giants star listened, usually attentively, over the next six hours as Bell testified that Bonds underwent dramatic physical and emotional changes during their nine-year relationship and admitted his steroid use to her in 1999.
