Bar Refaeli takes to the tennis court in a new ad showcasing just how fuss-free her new underwear line is.

The former Sports Illustrated swimsuit model is seen in the promotional video prancing around with a racquet hitting a few balls in just her under.me smalls, the Telegraph reported.

Showing how she can bounce around, serve an ace and jump on the spot without so much as a wobbling midriff or blob of cellulite, Refaeli – who dated Leonardo DiCaprio for six years – asserts herself as a sporty, almost tomboy-ish kind of girl.

Describing under.me as “a focused collection of beautifully-made basics that look good and feel amazing”, she explains that she believes underwear should complement the body and not ’steal the show.’ (ANI)
