It's Barbie Dahl, the one who posted the vid - check her profile.
It's certainly not Elaine, although they look similar there are definite differences:
1) Not Elaine's face, as urbanspaceman noted
2) Elaine doesn't have tattoos - Barbie does
3) Elaine has a mole on her right side, which can be seen clearly in a lot of her videos, Barbie does not
4) Elaine's boobs are smaller, especially after breastfeeding
to note a few.
Regardless, both Elaine and Barbie are incredibly sexy women.
