And the Union J singer’s ex girlfriend, Caterina Lopez, has shared an emotional message about being a single parent to the three-year-old, following his operation.
Taking to Instagram, the model shared an adorable snap of herself and her son, after he walked for the first time.
“Being a single parent and the sole provider for my child makes me mentally and physically exhausted,” she captioned the photo. “Especially these last two weeks with his second brain surgery has sucked me completely dry.
“Everytime I want to give up and cry I just look at Princeton and think of everything he has gone through and then I suck it up and keep going. Being a parent is all about putting your kid before yourself.
“His sickness comes before mine. Managing his pain comes before managing mine. His happiness comes first before mine. My dreams and career are put on hold so that he is #1 in my life and I would not have it any other way to be honest.
“I love my best friend and so blessed that GOD has let him survive everything he has been through because I can not live without him.”
