Justin Bieber has been soaking up the sun the last few days in Miami, and to say his vacation looks like a blast would be an understatement. The "Sorry" singer, who appears to be enjoying the single life [1], was spotted lounging on a luxurious yacht on Friday with Puerto Rican model Alexandra Rodriguez and his little brother, Jaxon [2]. In between wakeboarding in the crystal-clear water, Justin caught some rays at the front of the boat with Alexandra. He also took to Instagram to share adorable snaps of Jaxon enjoying himself, including a short video of his little brother hopping on his back for a spin in the ocean. We just hope he had Will Smith [3]'s "Miami" blasting in the background.
