Robel, however, said he interviewed Rowe last year and she expressed concerns about Jackson's parenting. "She referred to Michael as a sociopath and his children as being possessions," Robel said. Rowe is the mother of two of Jackson's three children.
Robel said Rowe also told him she and Jackson had "a plan" to speak positively about each other in public following their divorce in 1999.
District Attorney Tom Sneddon told Judge Rodney S. Melville he was bringing Robel to the stand to impeach Rowe's testimony.
While on the stand last week, Rowe swore that videotaped statements she made in February 2003 defending Jackson – following the damaging documentary Living With Michael Jackson aired – was not scripted.
Robel's testimony came as the prosecution neared the end of its case against Jackson, though Sneddon indicated that he may bring out one more surprise witness.
Jackson is accused of molesting a 13-year-old boy at his Neverland Ranch in February or March 2003, giving the boy wine and conspiring to hold the accuser's family captive to get them to rebut a negative documentary.
