Concentrate

Target identifiers are up and running, and I was able to sift out the identity of a video model; she should be the thumbnail still for this version of "Concentrate" by Xzibit.

With the help of Heavy, I've popped her as Stephania Bella, Italian-Cuban and very lovely. Intergoogle searching turned up her Model Mayhem page -- and that she's 5'3" tall with 39" hips -- plus the much better image you see here.
