Justin Bieber left little to the imagination when he stripped down to his underwear in one of his latest social media posts. The "What Do You Mean?" singer, 31, shared a carousel of photos via his Instagram account on Wednesday, September 10, where he was dressed in nothing but his tighty-whiteys while riding around on a segway. In the images, Justin appeared to travel along a gravel road in an outdoor area. He let the photos speak for themselves and did not caption the post.
