Leah is great. She came up thru the Anjali Kara/DiSanto productions (Killergram) mostly famously in their "dogging" scenes. They touted her as an Indian (Leah Joshi), but she now says she's of Middle Eastern (Arab?) descent. In any case, she's obviously not Anglo-Saxon/Celtic, but she's a product of South London and she's got the accent to prove it.
She became well-known in the states and internationally while spending a year in LA a little while back and featuring in many high-profile productions. I guess she now flies out to LA periodically to shoot new material.
She's quite a beauty (resembling Kim Kardashian a bit) and a very relaxed & sympatico performer.
