I don't think Lena is Natasha Starr based on the fact that here
is an interview Natasha Starr gave together with her sister Natalia for TribLIVEradio
in Pittsburgh USA which was published on Youtube on 03/12/2014.
Here are other porn videos of Natasha Starr: 1
As for Adele, well Adele retired from porn and she is studying so I guess she did it for her privacy. As an escort in London it is far more likely someone in London who is looking for an escort to recognise her from representative gallery pictures and porn videos than identify her from her crap pictures. And what were the chances for someone from her mates, neighbours and anyone else in UK to discover her forgotten/buried 3-4 years old porn movies by themselves?
I have been doing the pornstar list for some time now and despite the vast majority of pornstar escorts try to up their value by saying they are pornstars it is not entirely uncommon some former pornstars to not want to be associated with their escort profiles.
