That is a mugshot from a previous arrest.
Given the way they treated her character on the show, I'm not surprised. Of course sometimes the character the other characters dump on is actually their favorite, but there was such a vein of real nastiness in the stories involving her that it made me wonder when I watched the show.
Yep, and it didn't really make sense, as the rest of the characters were following a similar line of development only about five years younger.
The other actors real ages (Grace now 35, Kutcher 35, Prepon 33, Valderrama 33, and Kunis 30, and a mid teenager at the time) are about ten years younger. Lisa's character was trashed and she was left out of the group, and apparently, the only difference was age of the actress and or character.
...or it’s a mug shot...
