“I felt her purpose in my life when I was a kid and I would pray for my future daughter every single day and night. I know that most Moms would say please slow down time when their baby turns 11, but I have truly known her my entire life. Reading back on 30 yrs of conversations with God throughout my journal entries, it is evident that Maxwell was already living inside of my heart and my purpose,” she continued.

“Her birthday was FRANKLIN FARM LIFE HAPPY! She told me after she blew out HER 11 candles…’I made a wish that was for me and you and actually the whole family’ I said Maxi it should be your wish and she said ‘we have the same wishes Mom’ 3 days later on our way back to Cali she overheard me reading a text from my Dad and asked my mom sitting next to her ‘GiGi if my birthday wish came true already can I say it out loud or do I still keep it to myself?’ My mom told her to share it with everyone if she wanted to, especially if it had already come true…” Jessica wrote.

“Maxwell’s birthday wish was for her Papa Joe’s bone cancer treatment to work. It did. Thank you Maxi Drew for usin’ your wish on our family and most importantly, my Dad. You are mesmerizing, steadfast, intelligent, passionate, generous, loving, devoted, inspiring, enticing, confident, empathetic, powerful, intuitive, beautiful, DETERMINED, enlightened and FULL OF WONDER. The faith of a child is what keeps all of us ALIVE.”

The bone cancer diagnosis comes after he was diagnosed with prostate cancer in 2016. At the time, his rep told ET he was recovering from surgery following his diagnosis and that it went well.

We are wishing the best to Jessica and her family at this time.
