Leonardo DiCaprio's yacht day in Sardinia didn't go according to plan; he was enjoying a dip in the Mediterranean Sea with his girlfriend, Vittoria Ceretti, as they jetted around the crystal blue water in goggles. The fun didn't last long, as Leo soon emerged from the water and called out for help regarding a mark just below his butt. Clearly suffering from a jellyfish sting or a bite of some sort, Leo jumped beneath the yacht's outdoor shower where his model girlfriend took a closer look at the wound. The yacht's crew rallied to treat Leo’s injury, as they sprayed it clean and dried it with a towel. Thankfully, the sting didn't appear to be too serious.
