Just in case anyone's wondering (like me) the ad using Lolla/Alina's pics on Eros for "Samantha" is not her.

I was wondering the same thing.  Did you take one for the team and check her out?

I figured it out before then, and ended up asking the scheduler directly.
They admitted it.  
In any case I knew (or so I thought) that Lolla was somewhere else.
