Bar Refaeli has been enjoying the sun, some fun in the sand, and a whole lot of Q.T. in the pool this summer. The model splashed around with her brother and another pal in the pool on Saturday put their collective talents to good use creating this human pyramid, with Bar on the top and her brother bringing up the bottom. Refaeli Instagrammed (@barrefaeli) the shot and captioned it, "Three's company." Something tells us there are very few people who wouldn't want to join in on this human totem fun!
