Debbie Rowe was married to Jackson for three years

The late Michael Jackson's ex-wife, Debbie Rowe, is undecided over whether to fight for custody of their two children, her lawyer has said.

Her lawyer issued the statement after media reports that Ms Rowe had vowed to fight for custody of the two children she had with the late pop icon.

"I want my children," Ms Rowe said in an interview on Thursday with the NBC TV network in Los Angeles.

She is the mother of Prince Michael, 12, and Paris Michael Katherine, 11.

A third child, Prince Michael II, 7, has a surrogate mother.

Meanwhile footage of Jackson on stage days before he died has been released.

Film of the star recorded on 23 June - two days prior to his death - shows him rehearsing a routine at Staples Center in Los Angeles for a series of UK comeback concerts which had been planned for this month.

Jackson, who was 50, died after suffering heart failure at his Los Angeles home last Thursday.

His mother, Katherine, has been granted temporary custody of his children.

Tests

In a 90-minute telephone interview, Ms Rowe said she was prepared to undergo DNA testing to prove she was the children's biological mother.

She said she would seek a restraining order to keep Jackson's father, Joe, away from them, the channel's website reported.

"I am stepping up, I have to," she said.

Ms Rowe was left out of Jackson's will, which was drawn up in 2002 and details of which were made public this week.

"I have intentionally omitted to provide for my former wife, Deborah Jean Rowe Jackson," the document states.

Ms Rowe surrendered her parental rights in her divorce settlement with Jackson, but an appeals court later reversed the decision.

In 2003, Ms Rowe appeared in footage released by Jackson in response to a controversial documentary which raised allegations of inappropriate behaviour with children by the star.

In it, Ms Rowe described her family as "non-traditional", saying her children were her gift to Jackson.

"My kids don't call me mom because I don't want them to," she said. "These are Michael's children."
