A lawyer for Katherine Jackson has denied reports that Blanket Jackson's 13-year-old nephew Jaafar almost zapped the 7-year-old with a stun gun.
But Debbie Rowe - mother of Michael Jackson's eldest kids, Prince, 13, and Paris, 11 - is still concerned.
"Of course, I'm worried ... why would I not be worried about a child?" she told photographers Thursday. "He is their brother."
Asked if she's ever been to the Jackson home in Encino, Calif., she said, "I haven't been anywhere."

She declined to comment any further, telling photographers, "I don't know the specifics about anything." (The L.A. County Department of Children and Family Services has reportedly visited the Jackson compound at least three times.)
On Thursday, for the first time, Rowe visited the late King of Pop's final resting place at Forest Lawn Memorial Park in Glendale, Calif. She was granted access to the cemetery, but was not allowed near Jackson's mausoleum because of security restrictions.
