Michael Jackson’s children do not look anything like Michael Jackson. Debbie Rowe might take it to court. Joe Jackson was abusive to Michael and his siblings, which caused estrangement.
Michael Jackson didn't look anything like Michael Jackson. They may not be his children but it's hard to know what he would have looked like without all the "work" he had done to himself.
It doesn’t matter whether those children look like Michael Jackson or not (or even Debbie Rowe for that matter). They were born into the legal marriage of Jackson and Rowe and the paternity or maternity was never challenged. Legally they are the children of Jackson and Rowe.
