Paris Jackson I'm Helping My Mom During Hard Times

Paris Jackson is right by the side of her mom, Debbie Rowe, as she fights breast cancer.

Michael Jackson's 18-year-old daughter reconnected with Debbie after MJ's ex-wife was diagnosed a few months back.

Paris and Debbie got close after Michael died, but the teenager cut off contact for a few years ... until recently.

Now she's become a core part of Debbie's support system.
