Jessica Simpson, 42, proves she has kept the weight off and become more toned than ever

Jessica Simpson seems to be in the best shape of her life, which she proved again on Wednesday.

The 42-year-old blonde beauty showed off her very toned legs and slender waistline in new images from the fall collection of her eponymous clothing and accessories line. The former reality TV star was seen in cold weather looks while posing inside an old-fashioned diner and near a vintage car.

This comes three years after the ex of Nick Lachey lost 100lbs after she welcomed her third child – Bridie Mae – with husband Eric Johnson. 

So slender: Jessica Simpson seems to be in the best shape of her life, which she proved again on Wednesday

In one shot the Texas native had on a lacy black bra that revealed her toned tummy, as she added pleather shorts that highlighted her very muscular and tanned legs.

A black pleather shirt was worn open and she added hoop earrings, a heart pendant necklace and some very high platform boots in black with small chrome buckles.

She was also seen sitting in a diner booth.

The pinup had on a teal silky dress that made the most of her legs, adding platform silver heels with an ankle strap.

For this image she wore hoop earrings and bangle bracelets.

There was also an image of her sitting on top of the booth as she looked out a window.

For this set up the star wore her long blonde hair down her front as she added glossy lipstick.

Her outfit consisted of a maroon, green and cream colored paisley dress with gathered sleeves.

The movie star added shiny army green short boots with a platform heel and a round toe.

And there was also a photo of her sitting in a chair in what appeared to be a hotel room.

For this set up the siren had on a brown and beige print dress with a belt and matching cowgirl boots that had silver studs.

Her earrings were also the hoop shape here as her hair fell behind her back. 

Last week the star shared that her mini-me daughter Maxwell, 10, was the person who took a glamorous photo of her by a swimming pool in a back yard.

The Dukes of Hazzard actress was hawking a nameplate necklace that is being sold through her Jessica Simpson collection brand.

The child was seen in a long black T-shirt with her light hair pulled back at sunset as she held onto a professional camera while in a back yard by an empty swimming pool.

Simpson was seen with her long blonde hair falling down her back as she wore a strappy swimsuit that showed off her tanned body. Her face could not be seen. 

The star also noted that her fall campaign was ‘coming soon.’ 

The star also has son Ace Knute, nine, and daughter Birdie Mae, three, but they seemed to have the day off from work.

Jessica has done an incredible job at launching and maintaining her fashion brand, even buying it back last year to have full control of the company.

Simpson runs the label with her mother. Together they oversee the design if clothing, shoes, purses, sunglasses and jewelry, among other things.

Last week she shared an image of her two eldest children going back to school. 

‘These two had an amazing first day of school! I’m so proud! Heart is full. Growin’ up and ownin’ it. Happy kiddos,’ wrote the former reality TV star in her caption.

Kim Kardashian hit the like button. Her daughter North West is close friends with Maxwell and they often do play dates and sleep overs.

This comes after Simpson has been modeling her fall line for her clothing collection.   

In August the beauty starred in the new shoot where she had on Daisy Duke denim short shorts – which she wore beautifully in her 2005 film The Dukes Of Hazzard – with an orange paisley blouse.

Catherine Bach made short shorts famous when she played Daisy Duke on the TV series Dukes Of Hazzard which aired from 1979 until 1985.

That is why short shorts are called Daisy Dukes still to this day.

Simpson modeled the look beautifully. 

Jessica’s roller-skates were a sparkly bright pink and also a deep green color. The star was leaning on a vintage white car as she raised an arm in joy.

‘Don’t be a Hater, be a Roller Skater,’ she said in her caption.

‘Introducing the @jessicasimpsonstyle roller skates! Who needs to walk when you can roll…I promise I’m wheely good at this.’

‘Step into your confidence and roll onto something new! Introducing Rollstar! ✨’ it said on her Jessica Simpson Style Instagram account.
