'He makes my heart swell!' Size 22 model Tess Holliday shares sweet black and white picture of her newborn son Bowie's tiny feet

Tess Holliday has only had her son in her life for less than a week, but it seems that the model is simply head-over-heels for the tiny tot.

The 30-year-old mom took to Instagram on Friday to share a sweet black and white snap of her newborn son Bowie Juniper Holliday's little feet and to gush about her new arrival.

'Looking at Bowie's tiny feet & thinking about all the amazing places they will take him,' the proud mom-of-two wrote. 'He makes my heart swell.'

The photo shows Tess's hand with a glittering manicure, giving the sole of little Bowie's feet a rub with her thumb.

And, according to the model's followers on Instagram, the image also appears to show that baby Bowie's second and third toes on each foot are webbed.

'And his second and third toes are married! My baby boy has those webbies too,' said one fan, while another commented: 'He's gonna be an incredible swimmer!' 

The size 22 model and her fiancé Nick Holliday welcomed their first child together, Bowie Juniper Holliday, on Monday, June 13.   

At the time of his birth, Bowie weighed 8lbs, 10oz. and measured 22 inches long, and the 30-year-old mother-of-two is clearly over the moon about her new bundle of joy.

The baby's name is presumably inspired by the late musician David Bowie whom Tess publicly mourned on social media after his death in January.

Tess took to Instagram on Tuesday afternoon to reveal that they were getting ready to take their new son home.  

'Our handsome little guy is here, Bowie Juniper Holliday @nickhollidayco snapped this while I was dressing him to go home' she wrote. 

The picture sees Tess gazing down at her newborn son who is wearing a white onsie featuring large stars. 

Nick also shared a precious photo of Bowie on Instagram, writing: 'Cats outta the bag! Meet my little guy, Bowie Juniper Holliday.'

In the heartwarming black and white image, Nick and Bowie are nose to nose as they look at each other with love.

The social media star, who was born Ryann Hoven, is already a mom to a ten-year-old son, Rylee, whom she had with a previous boyfriend she no longer speaks to. 

Throughout her pregnancy, Tess became an even more vocal body advocate, sharing plenty of candid photos of her growing baby bump as well as nude photos to celebrate her changing body.

The plus-size model would often take to Instagram to hit back at critics who insisted that her baby's life was in danger because of her size. She appears to have given birth a perfectly healthy baby boy.

Tess, who publicly confirmed her pregnancy in January, celebrated her impending arrival in May by throwing a tropical-themed baby shower — which doubled as a housewarming party — and invited her nearest and dearest to come celebrate with her and Nick. 

There at their Long Beach, California home, guests were treated to a faux-Hawaiian getaway, complete with straw umbrellas, pineapple-shaped desserts, drinks with cute cocktail umbrellas. 

Just a few weeks before she gave birth, Tess spent her Memorial Day weekend flaunting her baby bump in a two piece swimsuit, sharing a photo of herself cooling off in a Los Angeles rooftop pool as she balanced a red Solo cup on top of her stomach.

'Showing off my #babybump skills,' she captioned the image, which sees her modeling a black bandeau top and black and hot pink striped bathing suit bottoms. 

Tess was joined by her friend, make-up artist Priscilla Ono, during her relaxing day at the rooftop at TenTen Wilshire, and the two were filmed with their hands on the pool's steps as they kicked their legs and splashed the water behind them.

In an interview with ET last month, Tess hit back at critics who insist her weight is a danger to her unborn child, claiming that her doctor had just given her a clean bill of health.

'I literally saw my OB/GYN yesterday and everything's fine,' she said. 

She added: 'He's happy. Everything's fine and I'm fine.' 

Tess also discussed with the publication her decision to post nude photos on social media, despite the criticism she ultimately receives from online trolls. 

'The more they don't want to see things like that or are criticizing my body, the more I want to do it,' she said. 'Since you are complaining about my covered-up photo, I am going to give you a nude photo to make you even angrier.'

Her latest racy snap appeared on her Instagram on a few weeks ago, featuring the pregnant mom displaying her bump at 37 weeks and poking fun at people who tell her: 'I can't tell you're pregnant.'

She wrote in the snap's caption: 'I will continue to live unapologetically, to thrive in this body, prove the naysayers wrong and laugh at the ignorance.'

It's just the latest instance that Tess has bared her bod for her fans — and critics — as she previously shed her clothes while seven months pregnant to pose stark naked for a sultry new photoshoot celebrating her size 22 figure.

Tess proudly took to Instagram on to share a nude photo of herself, which was taken last month during her shoot with The Telegraph. 

When captioning the portrait, Tess used a quote from her interview with the British publication, writing: 'What I want to say to you is that when people told me I couldn’t model, I would always think, I’ve literally had some of the s****est things happen to me and survived them, so me being a model is not the most ridiculous thing that I have had happen to me. I’ve never taken no for an answer.'

Tess ended the message using her famous hashtag #effyourbeautystandards, which she started using in 2012 to fight society's beauty ideals.
