Debbie Rowe wants guardianship of  Michael Jackson‘s children and is willing to go to court to make it happen.

The King of Pop’s ex is deeply concerned with the environment that the children – Prince, 17, Paris, 16, and Blanket, 12 – are growing up in, and believes their grandmother, Katherine Jackson, 83, is too old to serve as their guardian, reports TMZ.

“Katherine’s not connected with the kids or involved in their lives” Rowe, 55, allegedly told a friend.

Rowe is also concerned that Michael’s brothers are a negative influence. According to a source, animal-loving Prince has developed a penchant for vulgar language and is difficult to control. The former nurse particularly wants to get the children away from Jermaine Jackson, who she feels is “just plain creepy and extremely inappropriate,” according to the website.

She’s said to have no issues with T.J. Jackson, the children’s co-guardian, but fears that because of his own career he’s away from them too much.

While Rowe is only the biological mother of Prince and Paris, she wants to be appointed Blanket’s guardian, too. She’s yet to file legal documents asking for guardianship, but if found successful she plans to move the children to her ranch in Palmdale, Calif., where she breeds horses.

Rowe and Jackson were married from 1996 to 1999. Shortly after Michael’s death in 2009, Rowe reached a settlement with Katherine Jackson, which gave her rights to supervised visitations.

Last fall, Rowe attempted to become Paris’ co-guardian after the then-15-year-old attempted suicide.
