A woman has caused a stir online after sharing a naked photo of her cradling her newborn that had an "embarrassing" optical illusion.

Abby Gilmore shared an adorable photo of her holding her two-week-old son Mason in the shower. But while the mum-of-three captioned the image with a touching sentiment for her "little man" — her followers noticed something else going on.

As Abby tenderly holds her bub, he appears to be protecting her from flashing her boobs.

But one eagle-eyed fan pointed out, it looks as though her nipple was on display.

"Omg I thought his lil heel was a nipple," one fan pointed out.

"Totally thought it was a nipple! Then realised it was foot...." another said.

"Hahaha I zoomed. Not gonna lie," one fan wrote.

While one admitted she "wouldn't have even noticed" the apparent nip slip, but since it had been pointed out they "can't unsee it".

Many others admitted to having to "look twice" at the tender snap because of the embarrassing optical illusion.

Despite originally writing a sweet message to her little boy about how his birth had made life "content", Abby later amended the caption to address the many comments.

"Ps that's his foot, not a nipple," she wrote, along with a laughing emoji.

Her full message to Mason talked about the amazing connection the pair had formed in the short time since his arrival.

"It's amazing what one little boy can do. You've made me relax. You've made me feel content. You've made me enjoy this time again and most importantly, you've made my heart feel so complete little man," she wrote.

Adding: "Luckiest Mummy to have my 3 beautiful kids who share the strongest connection already."

Mason is the first baby for Abby and her boyfriend Leighroy Wellington. She already shares two older children, Arlo and Milla, with her ex-partner Jake Stringer.

She split with the Essendon player signed in mid 2016 and has become vocal in the "mummy blogger" community — sharing details of her life with the kids and running workshops for women.

She regularly shares brutally honest posts about pregnancy and motherhood, telling her 109,000 followers her boobs were "veiny" when Mason was born as he was desperate to feed immediately.

Mason came out of his sleepy state last night! He wanted to suck suck suck but I wanted to sleep sleep sleep. By the looks of my veiny boobies my milk isn’t too far away so I know I’ll be very uncomfortable soon and having to be feeding him even more often for relief. If you’re a first time mummy, or just not sure of something make sure you’re asking for help. I asked the nurse for a dummy last night which saved our sleep as I knew my poor nips were being used as one and avoiding cracks and blisters at all cost is crucial for sticking this part out. I’m quite sore in the tummy today but am recovering quite well. The girls will be up today, I wish you could all see how much they bloody adore him it’s actually just so gorgeous. Enjoy this time mummas, and don’t put expectations on yourself because you just don’t know what a little human is capable of or what you’ll need to do in order to make it work - Our dummy last night was a bloody life saver. I didn’t pack one because Arlo never took one! Rookie mistake 😂💙👏🏻 #newborn #MasonJames

In another post she described how hard breastfeeding was, describing her first few days as "rough".
