Bar Refaeli Shows Off Flawless Figure in Ad For Her New Underwear Line (VIDEO)
If this isn't motivation to hit the gym before summer, we don't know what is!
In a new ad for her underwear line, under.me, model Bar Refaeli plays a round of tennis in a sports bra and underwear -- and not much else!
It looks like the 26-year-old has some nice moves on the court!
Is it just us, or does this make you want to sign up for some tennis lessons?
