Mystery girl in orange bikini arcing her back to untie her strings without touching them

At 2:30 of Cyndago's Blonde Boyz music video, there is a 3-second clip in the background of a thin/fit girl with wet dark hair in an orange bikini sitting on the side of a pool, arcing her back so that the back string of her bikini comes undone. The clip is clearly taken from some other professional source, and not recorded for the music video. I've checked stock footage databases, as well as multiple porn sites, and just can't find it. I'd like to know either the video where this clip comes from, or the name of the girl. I have no where else to turn to, please help.
