Jack Osbourne's wife Lisa Stelly is reportedly an "unbelievably devoted mom".
The 26-year-old television star welcomed daughter Pearl, his first child with Lisa, on April 24.
Lisa is completely committed to motherhood and has transformed her lifestyle.
"[Lisa] is like Supermom," a source told Us Weekly magazine.
"She made this huge transition from model and party girl, to wife and unbelievably devoted mom!"
Lisa studied parenting immensely before Pearl arrived.
She wants to impart her knowledge to other new mothers via the internet.
"She started a mommy blog [RaddestMom] because she has literally read every book, and is becoming a baby expert," the source said.
"She would like to maybe write a book for first-time moms -- it's something she has started thinking about."
Jack married Lisa in Hawaii on October 7.
Only close family and friends were in attendance.
It was a family affair, with Jack's sister Kelly serving as a bridesmaid and mom Sharon turning 60 during the Hawaiian getaway.
