In the Kgirl world there is very little difference in the look of a true 25 year old and a 35 year old. I have only seen Luca twice but I think she is super attractive no matter how old she is. Trust me, I know they are always 10 years or more older than they look.
I remember one of the first girl's I saw at the former Bella's (the predecessor to EPM), said she was 26 and we laughed because I was the inverse at 62. When things came out at it's demise her true age a year later was pushing 40. They have the knack to make themselves look and act younger to throw us off and suck us in. A couple of the other girls that told us they were 25 or so and moved to California instantly became several years younger and they never aged in their ads.
Instead of the name game (which it is because they all have made up names), it's also the age game. All part of the fun and mystery.
