Posing in a Hong Kong bathroom in the swimsuit which had cut-out sections at the side, the model wrote: ‘Wearing my girl @melissaodabash.’
She wrote on a picture of herself from the side, she added the caption: ‘Don’t worry, he’s still here,’ next to a cry-face emoji.
Vogue’s soon-to-be sister-in-law Pippa Middleton is said to be expecting her first child at the same time as her.
And on Sunday, she slipped into a bikini in the garden just hours after claims that another Matthews baby was on the way.
That morning, it was reported that James Matthews, the older brother of Vogue’s fiance Spencer, was ‘overjoyed’ to be expecting his first child with wife Pippa, who happens to be the Duchess of Cambridge‘s little sister.

Currently bumping along nicely with her own pregnancy, Vogue shared a bump picture as she enjoyed the London sunshine.
The Irish model looked glorious in a little golden bandeau bikini, exposing her pregnancy shape as she turned to one side and posed while standing on a garden bench with her dog.
She wrote beside it: ‘I should be packing but it’s sooooo sunny and I have a new bikini and sunglasses!’
Spencer’s gorgeous bride-to-be also wrote ‘I love my bump’ beside the picture as she caught some rays.

Vogue posted side profile shot after being forced to deny she photoshopped her baby bump in a front-on shot last week.
The Irish beauty lashed out at trolls, explaining how two angles looked so different to one another.
‘These photos were taken within half an hour of each other,’ she explained. ‘Front on no bump, side profile POW there he is! So glad my bump has finally popped.
‘I never alter my body in any pictures, if you can’t see my bump it’s just because of the angle although I may only take side profile shots from now on!’
B UT Spencer and Vogue have just got back from a glorious babymoon in Crete.
Bidding farewell to the holiday spot, they posted a loved-up holiday snap via Instagram on Thursday morning.
The happy couple looked besotted in the sunset snap, which both uploaded just hours after Vogue took to social media to slam claims she had digitally altered pictures of her baby bump.
Vogue, 32, and Spencer, 28, put on a cosy display as they posed in front of the Greek sunset, with the Irish TV presenter shielding her growing bump in a flowing yellow maxi dress.
Daddy-to-be Spencer captioned his post: ‘Last night was magical… We are FAMILY… Can the Little one hurry up already @voguewilliams?’
Meanwhile Vogue wrote: ‘The end of our amazing holiday… there is nobody I would rather be with @spencermatthews.’

The couple’s sun-soaked getaway came after Spencer and James’s multi-millionaire father David Matthews was arrested and charged with sexual assault by French Police.
The 74-year-old was released on bail last month pending further investigation, and Spencer it yet to comment publicly on the news.
A spokesperson for the family said: ‘David Matthews categorically denies the allegation and unequivocally contests the untrue and scandalous accusation.’
