Aaron Carter's Family Wants His Money to Go to Son, No Fights Over Cash - TMZ

Jane says she and Aaron's siblings still haven't met Prince -- the mother of Aaron's ex-fiancée, Melanie, currently has custody.

She adds, however, the fam would really like to have a relationship with Prince and Melanie.

For those unaware, Aaron's twin sister Angel filed a petition this week to serve as administrator of Aaron's estate, and Jane tells us she asked Angel to take on that role.
