Tom Brady channeled his inner Irina Shayk while chilling on his yacht this week ... ditching his shirt and showing off his shredded bod just days after his apparent new lady went topless on vacation with Bradley Cooper.
TB12 has been hanging in Miami as the model spends time with her ex on a luxurious Italian trip ... and he seemed to be totally relaxed as he soaked up the sun.
Brady -- who will have an open fall schedule for the first time in his adult life -- still looks ready to suit up right now .
