And the 33 year old revealed her four year old son was ecstatic with the outfit as he wanted the little one to be named after the US president.
"Thanks to @oh_arthur for making this very cute baby grow," she captioned the shot. "George is very happy as he is wanting to call the baby @realdonaldtrump."
However, some of her 436k followers weren’t as impressed by the joke costume.
"Unfortunately it's not a funny joke. Nothing about that man is funny & the awful things he says & does should not be made light off," one replied. "Please next time pick your jokes a little more carefully."
"The actual Donald Trump causes a lot of pain and suffering for families and children. Some "jokes" should be private," another replied.
And a third simply branded it "disgusting".
But others rushed to defend the expectant mum, and told critics to "get over themselves".
"People really need to get over themselves. This photo wasn't posted to talk about the highs n lows of people, it was posted to express what a little boy wanted to call his baby brother," an Instagram user said.
"Love it! My son thinks Trump's name is hilarious also (I think everyone knows why!), he also thinks Trump's hair resembles his lion headed bunny rabbit.. this MUST mean we follow Trump too #hatersgonnahate," a fan joked.
"Ffs this is a baby gro seriously !!!! Really have people got nothing else more serious in there life other than to send you hate !!!! Ignore the haters enjoy rest of your pregnancy and chuff em x (sic)," another responded.
Danielle was forced to hit back at haters herself, after a series of critical messages.
The former Big Brother star, who recently sparked speculation over whether she had already given birth, added: "Shame on me!! It's a joke my 3 year old son likes the name trump no shame here!!"
