Things are going from bad to worse for Donald Trump - who’s received an Insta-roasting from a former Miss USA finalist.

Mexican-American former Miss Colorado Marybel Gonzalez took to the picture sharing service to give the outspoken tycoon a piece of her mind.

She lashed out at Trump after he announced his bid to become the Republican Presidential candidate with a rant about illegal immigrants.

Mexican migrants in particular bore the brunt of his fury - as he vowed to construct a gigantic wall across the border to stop the “flood” of people he said were mainly drug dealers and rapists from moving north.

His speech saw NBC dropping him as host of “The Apprentice."

The network has also, alongside Univision, decided not to screen the Miss USA and Miss Universe pageants - of which Trump is co-owner.

And he’s now been blasted by Gonzalez, whose post has already been liked more than 144,000 times.

"When I watched your ill worded and completely erroneous speech, the only thing that resonated with me was the level of ignorance in your words,” she wrote.

She castigated “The Trump” for saying all Mexicans who move to the USA are rapists.

“A rapist is a violator, and exploiter to be more precise. When you singled out a community and ignorantly generalized a population for the benefit of your campaign, you committed the worst exploitation,” she said.

“When you belittled the people of a country for the sake of a vote or an applause you acted in an unjustly manner to benefit your needs.

"Further, when you now negate other girls the opportunity to be present and heard in a public forum you are blatantly robbing them… if I am a rapist by the simple fact of being Mexican, then what do these actions speak of you?”

Gonzalez signed off the post with the signature: “A very Mexican, not rapist, Miss Colorado USA 2012, Top 10 Miss USA finalist.” Trump has not commented on the post.
