I could be mistaken, however I think Jen is Angel/Justine, who adverises regularily on BP, Eros, Cityvibe & etc.

Apparently Angel/Justine is no longer advertising on BP, Eros, or Cityvibe-her ads ran for several years. What makes me think that Jen and Angel/Justine are possibly one and the same, is that she used the same photo in a "Jen" ad that she used in an "Angel" ad. Not a for sure way to tell I admit. You can check out Angel at-

Apparently Angel has removed her website.

I doubt if Dodda places ads on BP, CV, or Eros
