The lawyers representing Michael Jackson's family in its lawsuit against AEG Live have reportedly been taking a hard look at Debbie Rowe, the mother of his kids Prince and Paris. MJ's mother, Katherine, is reportedly worried that she'll testify that he isn't the biological father, which could torpedo their claims for damages.
However, TMZ says that during her deposition, AEG's attorney's didn't ask Debbie anything about the kids' paternity. The site also points out that under California law, when a married woman gives birth, the husband is presumed to be the father unless proven otherwise. And, of course, Debbie has signed off on every custody agreement, including the one after Michael's death that split custody between Katherine and the kids' uncle TJ.
