According to her Twitter page, which can be found by googling her name, the woman in those videos is a transgender recording artist named Nikki Exotika.  She is using the same "handle" (nikkibarbiedoll) as the woman in the BP ad but I have not seen anything that has her using that same email address.

Phone number leads to an ad for "Paris Houston" with the same photos.  TER review is old so there is no link to a current ad but the review seems to describe the gal in question.  Maybe she has improved since 2007.

Great find.  also if you click on the video of hers thats titled "Nikki Exotika BIO" she talks about herself and explains how she's half swedish & half puerto rican (just like the bp add states) and then goes on to explain how she started taking hormones when she was younger to start her transformation so its the same gal/tranny but just posting under the name of Paris on her bp add.  Man I'm so glad i didnt decide to TOFTT and trek all the way down to see her/him.  Once again, another reason to love TER.  Good looking out guys!
