The Daily Grind Video

Don’t look now, but there is a nearly nude model swimming in her undies!

Fittingly, Bar Refaeli stripped down to her underwear to promote her new underwear line

The 27-year-old model is seen lounging on a chair reading a book in the advertising campaign, before she decides to jump into the pool wearing a thong and a long-sleeved white shirt.

In the black and white video, Bar looks geek-chic wearing black glasses that she doesn’t even bother to take off when she goes in for a sexy swim.

Bar’s underwear line was launched in April and this video is the third installment of the on-going video series.
