This is #1 on Google Trends right now and has been high up on it all week. She has a big fight coming up this weekend against Cristiane "Cyborg" Santos and since she's the most famous female MMA fighter and quite pretty it makes sense.

The only thing is that her appearing in Playboy seems like a rumor and nothing more. I'd be shocked if she did Playboy at this point in her career or ever. 

Here are some pics and vids of Gina I've posted in the past...
