Busty Babe in Surrogates Trailer

[SN4P3]

Anybody know who she is? Search the trailer on youtube. It should be about 2:30 mins long. She is in two parts, one, she shows her clevage wearing an amazing low cut dress, it happens so fast it's hard to ID. But at 1:27 it shows her up close. Who is she? I want a closer look at her tits but can't seem to track her down.

Thanks
