Sorry it's taken so long to answer, but our Zoe is an elusive lady! From what I can gather, and this is little bits of info taken from a number of websites, her full name is Zoe Lazarus and after her brief flirtation with pop stardom, she moved into advertising. She first joined New York ad agency Ogilvie & Mather, and this year joined the London office of global agency Lowe & Partners as a co-director (no less), so she seems to have done pretty well for herself.
I'd make a good stalker, I would. :-)
