Kourtney and husband Travis Barker welcomed son Rocky Thirteen last November.

Not long after that, the 45-year-old went back to work filming her reality show with her family, The Kardashians.

Now, Kourtney has confessed to the postpartum feelings she was having at the time.

The reality star shared a behind the scenes photo to her Instagram while shooting promos for the fifth season of the show – something she admits now she did not want to do.

As she stood in front of a green screen, the mother of four did not smile, nor seem to be having any fun.

Her tight beige dress hugged her hourglass figure, showing off her post delivery belly bump.

“I was 3 months postpartum and not feeling quite ready for a big shoot like this where there’s lots and lots of people watching me all day,” she wrote in the caption.

“And even though my baby boy was with me all day on set it’s not the same when I’m covered in makeup, in high heels and wearing a dress versus our snuggly days at home in pajamas.”

‘A BEAUTIFUL LIFE’

However, coming out of her postpartum period, Kourtney said she has since shifted her mindset to focus on the positives in her life.

“I am so blessed to be able to bring my baby to work. How fun to get to be glammed up when I’ve been home for months in pajamas.

“How blessed to get to work alongside my sisters and mom…we really have so much fun together!

“What a beautiful life!”

In the comments section, fans praised her down-to-earth confessions.

“On behalf of postpartum moms everywhere…thank you,” one person commented.

This is what’s up. Normalizing and embracing post birth bodies,” a second echoed. “Major kudos to her.”

“This is why you’re the best Kardashian,” a third gushed.

BIRTHDAY BEAUTY

Kourtney has been especially candid about showing off her true body.

Last month, she shared a series of photos from her 45th birthday trip with her family.

The Kardashians star shared colorful photos including a view from her luxe beach house, a gorgeous sunset, family selfies, and silver and red balloons.

However, the photos that grabbed fans’ attention the most were Kourtney showing off her post-baby body.

On the first slide, the TV personality pursed her lips and posed in the sand on a dark blue bench while wearing a tiny bikini and shielding her eyes from the sun with thin black sunglasses.

Behind the star was a yellow beach house with a sign that read, “RJ’s Water Sports Paddleboards, Kayaks, and Jet Ski rentals.”

In two other snaps, Kourtney showed off her bare feet and toned legs while enjoying time by the crystal-clear water.

The mom of four wore her black hair in a messy bun and stunned in an oversized red graphic T-shirt.

Family members were quick to praise the former Keeping Up With The Kardashians star, and how amazing she looked.

“45 never looked so good,” her Blink-182 hubby commented.

Kourtney’s stepdaughter, Alabama Barker, 18, said, “Yes bad b***h!”

“A dream,” wrote Kourtney’s other stepdaughter Atiana De La Hoya.
