Anytime someone or something is dubbed as "the world's hottest," version of whatever they are you should stop and take a look, right?

For instance, if you heard about the "world's hottest chip" you'd have to taste it, right? In the same vein, when you see someone is the "world's hottest grandma" you have to take a moment out of your busy day to see what she is all about? Of course you do. Anything else would be wrong.

Gina Stewart is known as "the world's hottest grandma" and she just celebrated her 50th birthday with a very provocative photo shoot for her 268,000 Instagram followers. This isn't the kind of grandma who's hot because she's standing at the stove making cookies for the grandkids.

Stewart is from Australia but really started making a name for herself in the United States over the past few years. What do you think, does she live up to her name?
