so cute and sweet, At the ages of 17 and 19, Justin Bieber and girlfriend Selena Gomez may think it’s a tad too early to be thinking of starting a family of their own. the couple took Justin’s young half siblings e they were having a whale of a time as they played with two year-old Jaxson and four-year-old Jazmyn to the beach in Malibu.

Jaxson and Jazmyn are Justin’s half siblings from his father Jeremy’s second marriage.

His mother Pattie brought him up in Canada as a single mother, but he has remained close to Jeremy and earlier this week was spotted out with his father and siblings at an restaurant and amusement arcade.
