The former TOWIE star, 26, shielded her blossoming baby bump in a chic monochrome co-ord, as she shared a number of playful snaps of her outfit on Instagram.

The reality star was effortlessly glamorous in the two-piece, printed with a black and white tribal pattern all over.
The shirt, adorned with quirky fringe detailing, remained sophisticated with soft chiffon sleeves, and a subtly plunging neckline.
Tying in a chic striped ribbon belt at her waist, the wrap-around skirt then concealed her baby bump from view - before cutting off high at her thigh in a sexier touch, to leave her long and slender pins on show.

Adding height to her frame with towering black heels, Ferne accessorised with statement drop earrings to glamorously tie her look together.
Sweeping her hair into a low ponytail and adding bronzer and a nude lip, the TV personality was every inch the glowing mother-to-be as she documented her night on Instagram.
First sharing a full length shot, Ferne then snapped a quick selfie of her proudly cradling her bump, captioned: 'There is my baby in there I pwomise but this outfit disguised it! What's everyone up to on this fine morning? let's spread #love' (sic)
Pregnant: Ferne is expecting her first child with ex-boyfriend Arthur Collins, who currently faces trial for an alleged nightclub acid attack
Ferne is expecting her first child with ex-boyfriend Arthur Collins, who currently faces trial for an alleged nightclub acid attack.
It was reported earlier this week that the former TOWIE star had gone to visit the 25-year-old scaffolder and businessman at HMP Thameside in south London in the past two weeks.
Ferne split from Arthur earlier this year, amid allegations that he carried out an acid attack at an east London club that left 22 people injured.

A source stressed that the couple were 'certainly not' rekindling their romance, claiming that Ferne was visiting Arthur to discuss matters surrounding their unborn child.
A source told The Sun: 'They are most certainly not back together and she has no intentions of doing so. But she saw him to discuss certain matters, given she is carrying his unborn child. She clearly didn't want to be seen as she went in and kept a very low profile.'
The insider claimed that Ferne was keen to keep a low profile and arrived at the Greenwich prison, ahead of Arthur's trial in October, wearing a hoodie.
MailOnline has contacted a representative for Ferne for comment.
