Who is this Blond Girl?

[Arshem]

I've seen this girl at several sites, sometimes under the name of Gia. I'd like to find out who she is and get some more pics of her.

Can anyone ID her?

Here is a picture of her:

edit: picture link doesn't work


Also, here are 2 links:

and here she doing a girl-on-girl scene obviously taken from a movie.

If possible, can someone ID the 2nd girl?

Thanks in advance.
