Chrissy Teigen shows off a VERY flat tummy less than a month after giving birth to her third child

Chrissy Teigen looked ready to stock up on her daily essentials with husband John Legend when the couple headed out to Los Angeles for a trip to Costco on Thursday.

The 37-year-old Cravings founder walked across the parking lot in high-waisted gray leggings and a white sports bra.

Chrissy’s stomach looked incredibly flat despite giving birth to her and Legend’s third child less than a month ago via C-section.

She changed into a comfortable long cardigan and tied her hair up in an olive-green baseball cap.

Chrissy held hands with her eldest daughter, six-year-old Luna, as they made their way to the members-only warehouse store.

Meanwhile, John cut a sleek figure in a Gucci hoodie and distressed denim jeans.

The 44-year-old hitmaker wore aviator glasses over his eyes and slipped into sparkly white sneakers to complete the look.

Chrissy, John, and Luna were accompanied on the shopping trip by a masked woman, who may have been one of the couple’s babysitters or a close friend.

Missing from the action were Chrissy and John’s four-year-old son Miles, as well as their newborn daughter, Esti.

Costco, which has 46 stores in the US and Puerto Rico, offers great deals on home goods, electronics, appliances and more.

And the growing family has plenty of reasons to buy in bulk after Esti’s arrival last month.

John first shared the news while performing at a private show, where he told the crowd that he and his wife welcomed the “little baby this morning.”

“What a blessed day,” John gushed, adding that although he “didn’t get much sleep,” he felt “energized” after spending “a lot of time” at his wife’s side in the hospital.

Days later, Chrissy officially announced her daughter’s arrival in January in an emotional Instagram post.

It included a lovely image of Luna and Miles cradling their little sister, who was wrapped in a fuzzy blanket.

‘She’s here! Esti Maxine Stephens – the house is packed and our family couldn’t be happier,” Chrissy wrote.

‘Dad sheds tears of joy every night to see Luna and Miles so full of love, and I’m learning you still need c-section diapers!?

We are in bliss. Thanks for all the love and well wishes, we’re sorry! X’, the Chrissy’s Court presenter finished the caption.

A week and a half later, John shared his own photo holding Esti with his Instagram followers.

While recovering from her C-section, John told her PEOPLE how he’s been helping take care of Esti.

“Obviously I can’t breastfeed her, so I help feed her when we use the bottle,” the EGOT winner said Wednesday. ‘I’m happy to change diapers. I’m also good at making her burp.

The doting father also revealed that he started singing to his newborn.

“I started singing to her a bit,” he said, noting that his wife is also “good at lullabies.”

Overall, John hopes that by taking on more responsibilities he is relieving some of the stress on Chrissy.

‘I try to help out as much as I can, you know, to give Chrissy a break.’

Later in the interview, John talked about his and Chrissy’s older children and how they were “not sure” if they would like the newest addition to the family.

“Our older kids really like being big brothers, which we weren’t sure about,” John admitted, adding that “it seemed like they might be jealous when Chrissy was pregnant.”

But Esti’s arrival changed everything for Luna and Miles, thus easing their parents’ fears.

“Since Esti was born, they’ve been so loving and wanted to hold her and feed her, they just wanted to be good siblings,” he gushed.

Chrissy gave birth to her third child on January 13, and when asked how she is doing, John said it’s “a recovery process” for the cookbook author.

Chrissy decided to skip Sunday’s Grammy Awards to stay home with Esti even though John was nominated for three.

He also took the stage to perform DJ Khaled’s GOD DID with Jay-Z, Lil Wayne, Rick Ross and Fridayy.

Before the red carpet arrivals, the model uploaded a photo of herself hugging Esti. Captioned: ‘Happy Grammy Day! she had a dress fitting, looked around and realized… what the hell am i trying to try on here. I can’t get up lol

Chrissy has been largely recuperating at home for the past few weeks, having only been seen in Los Angeles a few times.

To aid in her recovery, the influencer recently revealed that she has been using Bellibind brand postpartum tummy wraps.

‘Sent love and healing to my womb today!’ wrote Chrissy, who shared a picture of herself sporting the gear on her Instagram Story.

‘Thank you so much @bellibind!’ she added. ‘What a beautiful experience today! Sorry for the snoring 🙂 I’ll be gifting this to all the new moms I know!

According to New Life Birth Services, the belly wrap provides “hip and lower back support,” helping the mother recover much faster.

The emotional and physical effects are so positive that many mothers describe it as “a big hug.”

Chrissy announced she was expecting on Instagram in August, sharing photos of her blossoming baby bump with fans.

The happy news came almost two years after she and John lost their son Jack at 20 weeks pregnant. She later revealed that the death of her late son was the result of a life-saving abortion, not a miscarriage as she originally claimed.

She explained that she made the “difficult decision” to terminate the pregnancy after accepting the fact that she and Jack would probably survive.

‘Let’s call it what it was: it was an abortion. An abortion to save my life for a baby who had absolutely no chance. And to be honest, I never, ever put that together until, actually, a few months ago,” Chrissy confessed, according to THR.

Chrissy and John got married in 2013 and will celebrate their 10th wedding anniversary in September.

The couple met in 2006 while on the set of the music video for John’s Stereo, and Chrissy revealed to Cosmopolitan in 2014 that they “hooked up” after filming.

Five years later, the All Of Me singer would propose to the model.

They welcomed their first daughter, Luna, in 2016 and son Miles was born two years later.

In an interview last year, John admitted that he was “more selfish” and “not a great partner” in the early days of his romance with Chrissy.

‘Even though he was very interested in her and very excited to be with her. He was still selfish,’ he explained. “I was in my late 20s and not yet ready to be the committed partner that I am now.

‘When you stop being so selfish when you think not only about the joy you get from a situation and the pleasure you get from it, but also about your responsibility and your commitment in that situation. You just grow and mature,’ John said.
