One user joked, "If I buy this can I look like that?"

Jessica has been on a fitness journey since welcoming her daughter, Birdie Mae, in March 2019.

In July, the Dukes of Hazzard actress celebrated her 40th birthday by posting a picture to Instagram of herself wearing a pair of jeans that she ‘couldn’t get over her hips for the past 14 years’.

"I was in complete shock. It was a good 40th birthday present. I've tried to pull those things over my hips so many times. I just thought my hips, from having babies, would never go back, but the jeans went up,” she told People.

The star’s trainer, Harley Pasternak, previously opened up about how he whips his clients into shape, revealing he tells them to get seven hours of sleep per night, avoid alcohol and ditch the afternoon caffeine hit.

“Celebrities can struggle managing their time but it’s important,” he told The Mirror.

“Go to bed at a certain time, set an alarm and wake up at a certain time.”

“All my clients have a daily step goal. The first is 12,000 steps.

“You don’t need to go to the gym for this now summer is here. You don’t need to run, sweat or huff and puff – you could be on the phone to your mum, your clients, your friends… just keep moving, multi-task and enjoy.”

He also recommends his clients cut down on screen time by using their devices for one hour before bed.
