Necroing a bit here, but just stumbled on her scenes and looking for more info.
Disappointed to see she basically did a couple scenes then moved on, had the look to go far.
Resurrecting the conversation about whether she's had any work done -
At first I thought similar to many that she's just perfectly proportioned... But actually in at least the trailer for her GirlsGoneWild scene there are a number of instances where you can see what looks like a vertical scar under her left nipple, that looks a lot like a breast reduction/augmentation.
Again, it's ultimately neither here nor there, but for those who have a particular focus on such things, worth taking a look at.
Edit: Also, following on from those discussing whether it's her on Instagram, that profiles gone but there's still a model page at

Possible shes lost a bunch of weight and gone mainstream as the girl does look like a skinnier version of the one from the scenes and the names match up.
