Jessie James Decker, 32, models bikinis as she debuts her swimsuit line Kittenish

This month country singer Jessie James Decker has launched a swimsuit line for her brand Kittenish.

The 32-year-old songbird, who was born in Italy but resides in Nashville, has already posed in several of the designs for images shared to Instagram this month.

Ever since welcoming her third child, the beauty has been getting back into shape with daily workouts as she sticks to the South Beach Diet.

In one of the photos the star has on a light violet bikini that makes the most of her hourglass frame. ‘Swim is here sweet cheeks!’ she said in her caption. ‘For those asking my size I am an xs in bottoms and small and xs in certain Tops!’ she also noted.

Her hair is worn down in soft waves as she gazes at the camera.

In another shot, the wife of former football star Eric Decker has on a light pink two piece while she reclines on a lounge chair.  

She wed Eric in 2013 and in 2014 they welcomed their first child, Vivianne Rose. In 2015 she had her second Eric II and in 2018 her third, Forrest Bradley.

This comes more than a year after the siren lost 25lbs while on the South Beach Diet – she has said on Instagram she is now a size XS.

She showed off her slender figure in a bra top and small bicycle shorts as she raised her arms to flex them.

‘The top of this year I decided to really step it up in the gym!’ said the star in her caption.

‘Build more muscle, get my core in order and get stronger! I know my core will probably never be as strong as it used to be but damn it I’m gonna try!’

The crooner added, ‘I have goals and I’m not stopping until I’m there. What were your goals in January? Are you still sticking to it? #letsdothis #gettinstronger.’  

Earlier this year she said she had gained some weight.

‘On my tour I had gained some weight and on my 5’1 frame that can be a lot(All the short girls know what I’m talkin bout),’ she began.

‘I noticed when my jeans weren’t buttoning anymore, and I wanted to get back to myself and start feeling strong and healthy and energized again.’

She continued: ‘So I made a change right before this photo shoot and busted my butt! I did 100 lunges a day, squats, 100 crunches and couple mile walks ( I don’t love running) and stuck to a very strict program and lost 6 lbs in 7 weeks!!’
