That's an understatement. I think you need to remind yourself what she looked like just 2 years ago. Or even in 2020. Maybe even back in her Tumblr days as realbarbielifts or fractalacidfairy. She constantly looks drugged out, and has put on just enough weight to change the fundamental shape of her body. You can also compare the way her pussy looks. Quite the change in appearance.
Some of that is natural aging, sure, but as a porn star, her "tools" are her body. And as every professional should know, having good tools is one of the most important things to quality work. Spending your life getting high, alone, in your apartment, with minimal human contact, masturbating, and living online, are not the way to keep your tools in good shape.
There's no accounting for taste, everyone has different preferences, so other people may prefer how she looks now. That's fine, but the change has been fairly drastic over the years.
