Gervonta Davis' ex Ari BUYS New Body In Colombia!! (Pics)

Instagram star Ari - real name Ariana Fletcher - is a model/entrepreneur best known for being engaged to rapper G Herbo (whom she also has a son with), and for dating boxer Gervonta Davis.

But two weeks ago, Ari decided that she was done with Gervonta - and wanted to live the single life.

Now Ari's back in the news again. According to a medical page on Instagram, Ari flew to Colombia recently to get a full body makeover. The page claims that Gervonta's ex purchased a brand new body from Dr. Hector Plazas, a Colombian plastic surgeon, that's renowned for his butt surgeries and tummy tucks.

The page even provided what they claim are receipts.

The surgeries, according to the page happened in June - right before Ari's split with Gervonta. Maybe she wanted to live out her first HOT GIRL SUMMER with the new body???

Here are some recent pics of Ari, and her body looks a lot more voluptuous than we remember. 

Earlier this year G Herbo was facing a battery charge after an argument with his baby mama, Ariana Fletcher, allegedly turned physical ... according to TMZ.

According to Atlanta Police ... the rapper and Ari got into it Wednesday morning -- mostly yelling at each other -- but at some point, cops say Herbo assaulted her. Cops say he then left the location with their son but later returned ... and after officers spoke to him, they arrested him for simple battery.

Cops say Ariana sustained minor scratches during the altercation.
