The singer, as well as her mother Tina, regained control of the brand in 2021 after its parent company, Sequential Brands Group Inc., filed for bankruptcy earlier that year.

Simpson recently spoke to People and opened up about the inspiration behind her brand's new items.

'I get my design inspiration from everywhere, like a song I love or a piece of art. I love vintage fashion so I am always looking through archival prints and cuts,' she said.

The hitmaker went on to speak about how she had taken notes on style from the eldest of her three children. 

'I am very inspired by my [11-year-old] daughter Maxwell. Her pulse on fashion is so unique. She is an infectious trendsetter and always effortlessly confident,' she said.

Simpson also opened up about donning a bright green bikini top during her recent photoshoot. 

'It wasn't until I became a mother that I learned to celebrate what a woman's body can do. I am more confident now after three kids than I was at 25!' 

She is also a busy married mom.

Jessica and Eric wed in 2014 and have three kids: daughters Maxwell Drew, 11, and Birdie Mae, four, as well as son Ace Knute, 10.

This comes four years after the former reality TV star lost 100lbs thanks to her intense workouts that included walking 14,000 steps a day after welcoming three children with husband Eric Johnson.

She has said in the past that she got up to 240lbs when pregnant.

The former reality star admitted in 2019 that she lost 100lbs nearly six months after giving birth to her third daughter, Birdie. 

She followed a meal plan and walked 14,000 steps per day with help from celebrity trainer Harley Pasternak, and has since shared updates from the gym as she's maintained the weight loss through the years. 

'6 months. 100 pounds down (Yes, I tipped the scales at 240),' she wrote on Instagram when revealing her weight loss. 

'My first trip away from #BIRDIEMAE and emotional for many reasons, but so proud to feel like myself again. Even when it felt impossible, I chose to work harder.'

Harley told E! News at the time: 'It had to be more than just getting back from her baby weight, but how do I keep whatever I am doing now forever. That's why we are not a big fan of doing any extreme diet or radical forms of exercise.' 

Simpson told Hoda Kotb during an appearance on the Today Show in 2021 that she never weighs herself anymore, doesn't own a scale and follows her intuition with how she feels when picking out her clothes.

'I have no idea how much I weigh,' she said. 'Like, I just want to feel good and be able to zip my pants up. If I don't, I have another size. I have every size.'

In September 2022 Simpson said she is happy to 'make money off' the chatter surrounding her fluctuating weight.

The star acknowledges that her weight has been the subject of speculation for years, and it was actually one of the reasons she decided to launch her own fashion line, The Jessica Simpson Collection.

The singer -  told Extra: 'I decided, 'Okay, everybody is going to talk about my weight all the time, I might as well make money off of it and turn it into a business of selling clothes and acceptance.''

By contrast, in 2021, Jessica admitted to being hurt by the scrutiny she's faced. The blonde beauty felt there was an intense focus on her looks and her weight when she was younger.

She explained: 'There is a wonderful movement for body positivity now and the response to that portion of my story has been overwhelmingly supportive.'
