Gucci Mane's wife Keyshia Ka'oir has faced rumors that she's surgically altered her shape - by having 2 ribs removed.

Now there are new rumors - that the slender beauty recently got two MORE ribs removed.

Rib removal surgery is illegal in the United States but is going in popularity in South America and Mexico.

So what is "rib removal" surgery? It's not what you think. The bottom ribs are not actually "removed." Instead, a surgeon breaks the patients bottom ribs and turns them inward, so that when the bone heals, the rib will be twisted inward.

The popular transgender performer Amanda LePour explained it, in a recent interview:

'I've had my boobs done, and my lips done, my bottom lip reduced, and my bottom rib broken and pushed in—I think Raquel Welch and Cher did that, too. It's illegal in the US, but I had it done in Mexico. They break the floating rib in the back and push it in, so there's no scar
