With just one month to go until the birth of her daughter, the 31-year-old `Fashion Star` mentor has finally admitted defeat and abandoned her beloved stilettos.
The singer-turned-designer was reportedly heard telling a fellow shopper in Santa Monica store Fred Segal`s: "Only one month to go! I can`t wear heels anymore. I tried but it was too hard. Wearing heels is like a religion to me, so it`s tough!"
The baby will be the first for NFL star Eric Johnson and Jessica - who previously vowed to keep her heels on throughout the birth.
She joked to US Weekly: "I`m probably going to deliver my baby in [four-inch YSL heels] ... I went to the doctor yesterday and he said, `You`re going to need to get out of those heels!`"
Having gained 40lbs whilst pregnant, Jessica is rumoured to have signed a £2.5million deal with Weight Watchers to "lose a significant amount of weight" once the baby arrives.
A source told the magazine she had been planning to become a spokesperson for the company, "But then she got pregnant, so this was the perfect compromise."
