It's possible for Ava to be legitimately 30, but that would also entail some serious hardcore drug usage. In other words, unless she was a complete junkie, Ava's 35. At least. Remember folks, the adult world ages you in dog years.
Also, I'm pretty sure since Ava's hit the scene, her tits have remained the same size, just show in different outfits make them look bigger/smaller.
Whatever. It's obvious that Ava is going for as much money as possible, because wherever I turn lately, Ava's there. The amount of material she's put out in the last year is simply mindboggling. I'm guessing she knows her time is numbered and she wants to make as much money as she can.
