Sarah Stage poses nude at nine months pregnant

It took model Sarah Stage quiet a while to look visibly pregnant, but soon-to-be mom-of-two is finally, clearly, expecting — at nine months.

The 33-year-old became famous during her first pregnancy, during which she maintained washboard abs through. She only started to look really, truly pregnant late into her third trimester — and the same is true the second time around.

Just days from her due date, Sarah has showed off her baby bump in all its glory, posting a nude snap on Instagram for her fans.

In the picture, Sarah poses in profile, with one hand over her breasts and the other on her lower back.

She juts out her chest and smiles in a face full of make-up. The only clothing she wears is a floral robe that hangs off her arms and covers nothing. 

Sarah certainly hasn’t been shy about posing nude throughout her pregnancy. An underwear model, she’s gone repeatedly without clothes to document her changing body.

A week ago, when she first hit the nine-month mark (most pregnancies last about 40 weeks, which is close to ten months), she shared another nude image.

‘This pregnancy journey is almost coming to an end,’ she wrote. ‘I’m incredibly amazed of what our bodies are capable of achieving, growing a healthy baby inside our bellies is truly a miracle! Remaining positive through this whole experience has given me the extra strength I needed. After all, our thoughts lead to behaviors, behaviors lead to habits, and habits create our life!’

A more-clothed photo she uploaded on Sunday shows her in a black catsuit, fishnets, and thigh-high boots. She seemed to want to show off her Halloween costume early, as she may give birth before October 31. 

‘When you’re #9monthspregnant but still want to be festive and have fun LOL,’ she wrote in the caption for the image. 

Sarah has ‘enjoying the last couple weeks of this pregnancy’, according to Instagram — even if she has to regularly defend herself against critics who say that her minimal weight gain can’t be healthy for her unborn child.

‘It’s been quite the journey! I’ve been asked how much longer I intend to workout and I think next week will be my last week,’ she said, adding that she has decreased her exercising to two times per week and also lowered the intensity of her workouts.

Sarah has come under fire quite a bit during each of her pregnancies — though after facing down critics while pregnant with her first, she gave birth to a healthy baby boy.

Many have taken issue with the fact that she barely has a bump for much of her pregnancy, with quite a few noting that they would never guess she was pregnant without being told.

They’ve also criticized her frequent workouts and diet, which includes smoothies made with protein powder.

After one picture including the protein powder, some questioned if it was safe for pregnant women.   

However the company, Protein World clearly states on its website that pregnant and breastfeeding women can have up to two Slender Blend smoothies per day, as long as one of the shakes is used as a snack and not a meal replacement.

In September, Sarah celebrated her impending arrival with a lavish baby shower thrown by her close friends.

The occasion was so grand that she wore a Walter Collection gown from Walter Mendez as her friends and family paid tribute to her at the Regency Event Venue in Glendale, California.

Sarah looked amazing in the blush-colored dress, which featured an illusion mesh bodice and hand beading.

Her friends Isabel Alysa, Jessica Giselle, and Carrie Minter planned the fete for the soon-to-be mother-of-two, and she made sure to thank her pals when sharing photographer Von Jackson’s pictures from her gorgeous shower.

‘My beautiful friends @isabelalysa @jessicagiselle_ and @carrieminter went above and beyond to make everything so gorgeous!! Baby boy is already so spoiled and loved! #35weekspregnant,’ she captioned an Instagram image of her and her husband, Kris Jason, at the event.

Speaking to E! News at her shower, Sarah opened up about her workout regimen.

‘I am not working out as often. I am still working out from home and I am going to still keep working out while I still have energy,’ she said. ‘I’m doing everything from my e-book. I just lowered the weights and the repetitions and the intensity.’

Much like her first pregnancy, in which Sarah had a six-pack up until the day she gave birth, her Instagram feed is filled with comments from people who claim she is harming her unborn child with her fitness regimen and trim physique. 

Sarah revealed last month that she had gained 18lbs, and was presumably continuing to put on weight as she nears the nears the end of her pregnancy.

The fitness star gained a total of 28lbs during her first pregnancy, and she seems to be on track to gaining the total 25 to 35lbs that is recommended for the average healthy pregnant woman.

But it seems that Sarah has mastered the art of ignoring her haters, as she continues to speak candidly about her pregnancy and her unborn child’s health on her Instagram page. 

When one Instagram user accused her of doing ‘too much’ and trying to ‘perfect’ in the comments section of her recent workout post, Sarah hit back. 

‘I’m far from perfect ! Please read caption,’ she wrote. ‘Twice a week workouts are not too much . I chose to show you 1 per cent of my day, by choice.’
