Chrissy Teigen looked ready to stock-up on everyday essentials with husband John Legend as the couple stepped out in Los Angeles for a trip to Costco on Thursday.

The Cravings founder, 37 strolled the parking lot in high-waisted gray leggings and a busty white sports bra.

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

She layered up with a cozy longline cardigan and tucked her hair up into an olive green baseball cap.

Chrissy held hands with their eldest daughter Luna, six, while making their way to the membership-only warehouse store.

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

The hitmaker, 44, wore aviator shades over his eyes and slipped on bright 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 nannies or a close friend.

Missing from the action was Chrissy and John's son Miles, four, as well as their newborn daughter Esti.

Costco, which has 46 stores across the U.S. as well as Puerto Rico, offers killer deals on household products, electronics, appliances and more.

And the growing family has plenty of reason to buy in bulk following 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 a lot of sleep' he felt 'energized' after spending 'a lot of time' by his wife's side at the hospital.

Days later, Chrissy officially announced their daughter's January arrival in a heartfelt Instagram post.

It included a precious image of Luna and Miles cradling their little sister, who was bundled up in a fuzzy blanket.

'She's here! Esti Maxine Stephens – the house is bustling and our family could not be happier,' Chrissy typed.

'Daddy sheds nightly tears of joy seeing Luna and Miles so full of love, and I am learning you still need diapers with a c section!?

'We are in bliss. Thank you for all the love and well wishes - we feel it all! X,' the Chrissy's Court host ended the caption.

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

As she recovers from her C-section, John told PEOPLE how he's been helping care for Esti.

'Obviously I can't breastfeed her, so I help feed when we use the bottle,' the EGOT winner said Wednesday. 'I'm happy to change diapers. I'm good at burping her, too.'

The doting father also revealed that he's started singing to their newborn.

'I just started singing to her a little bit,' he said, noting that his wife also happens to be 'good at lullabies.'

All in all, John hopes that by taking on more responsibility he's alleviating some of Chrissy's stress.

'I try to help as much as I can, you know, to give Chrissy a break.'

Later in the interview, John discussed his and Chrissy's older children and how they 'weren't sure' if they would be fond of the family's new addition.

'Our older kids are really into being older siblings, 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 alleviating the parents' fears.

'Since Esti's been born, they've been really loving and wanting to hold her and feed her — just wanting to be good siblings,' he gushed.

Chrissy gave birth to their third child on January 13 and, when asked how she's doing, John said that it's 'a recovery process' for the cookbook author.

Chrissy decided to skip Sunday's Grammy Awards to stay home with Esti despite John being up for three nominations.

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

Ahead of the red carpet arrivals, the model uploaded a picture of herself cuddling Esti with the caption: 'happy grammy day!! had a dress fitting, looked around and realized…what the hell am I trying to prove here. I cannot get up lol' 

Chrissy has largely been recuperating at home these past few weeks, having only been spotted out and about in Los Angeles a few times.

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

'Sent love and healing to my womb today!' wrote Chrissy, who shared an image of herself rocking the gear on her Instagram Story.

'Thank you so much @bellibind!!' she added. 'What a beautiful experience today! Sorry for the snores :) Will be gifting to every new mom I know!!'

According to New Life Birth Services, Belly binding provides 'hip and lower back support,' helping the mother to recover much faster.

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

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

The happy news came nearly two years after she and John lost their son Jack 20 weeks into her pregnancy. She later revealed that her late son's passing was the result of a life-saving abortion, not a miscarriage as she originally stated.

She explained that she made the 'difficult decision' to terminate the pregnancy after coming to terms with the fact that she nor Jack would likely survive.

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

Chrissy and John wed back in 2013 and will celebrate their milestone 10th wedding anniversary in September.

The couple met in 2006 while on set of John's Stereo music video, with Chrissy revealing to Cosmopolitan in 2014 that they 'hooked up' after the shoot.

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

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

In an interview last year, John admitted that he was 'more selfish' and 'wasn't a great partner' in the early days of his and Chrissy's romance.

'Even though I was very into her and very excited to be with her. I was still selfish,' he elaborated. 'I was in my mid-20s, still not ready to fully be the committed partner that I am now.

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