OK, all becomes clear now, after a dig around on the net... these are
Big Brother Norway contestants Linni Meister and Kristian Hilberg. The tape was not
made in the BB house, but was (allegedly
) stolen from the couple while vacationing in Egypt, and then released to the media.
The television that is on in the background of the main clip is tuned to a Dutch station, which is why it's in Dutch. However, the extra pieces of post-sex video at the end do
show the pair speaking in Norwegian.
