London, April 16 : Israeli model Bar Refaeli left little to imagination after sporting a tiny bikini to promote the new Sports Illustrated issue in an advertisement.

Leonardo DiCaprio's girlfriend, who graces the cover of the 2009 issue, is seen lying on the beach against the waves in the promo for the magazine, reports The Sun.

The stunning 23-year-old had posed almost half naked for the cover and was seen posing in a string bikini, carefully pulling one of the thin straps down her hip.

Refaeli has previously stripped for swim-sports label Hurley. (ANI)
