By 2015, the 39-year-old had given birth to two children, Maxwell, 7, and Ace, 6, but due to her erratic weight, she had stretch marks and extra skin.
Jessica discusses her body-image issues in detail in her new memoir Open Book.
She didn't want to be personal without a t-shirt on since it affected her sex life with husband Eric Johnson.
Jessica made the decision to have a partial stomach tuck in 2015 as a gift to herself for turning 35.
She was travelling in St. Barts at the time when her doctor called with some serious concerns.
When a specialist advised the With You singer not to proceed about the treatment due to worries with her liver levels, she was two weeks out from the procedure.
According to Jessica, "He was forthright." "My plastic surgeon might have given the go-ahead for me to have the procedure in two weeks, but he wouldn't."
He warned her, "You could die," and recommended her to abstain from using drugs and drinking alcohol for three months.
However, Jessica, who is also the mother of 10-month-old Birdie, chose to "disregard" what the doctor advised and go forward with the procedure.
The reality star, however, wasn't happy with the results and ultimately underwent a full stomach tuck.
