Pregnant Jessica Simpson has given up heels

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."
