Scarlett Johansson wore a bikini yesterday for a boat ride with her boyfriend Nate Naylor. They were joined by some friends for their voyage out on the ocean, and the group was seen opening bottles of wine and fishing. The couple are off enjoying a week-long getaway in Hawaii, where Scarlett was seen in a teal bikini Friday. Nate and Scarlett have reportedly been dating for six months, but they just went public as a duo earlier this month. He was by her side for a sweet day-date two weeks ago, but Scarlett brought her brother Hunter along as her date to an Obama fundraiser she cohosted with Vogue's Anna Wintour last Tuesday.
