Even though Justin Bieber is a successful singer, taking care of his younger brother can be a challenge for him. Despite this, he and his girlfriend Selena Gomez always manage to find ways to have a good time with his little sibling. Recently, they enjoyed a day at the beach playing a “fun game” with two-year-old Jaxson. Selena looked stunning in a yellow dress and denim jacket, while Justin sported a matching T-shirt. However, Justin was so engrossed in the game that his pants ended up falling down. After a day of fun, the couple appeared weary and unkempt the following day, showing that looking after a child can be exhausting.
