Justin Bieber and Selena Gomez made it an all-in-the-family day at a Malibu beach on Friday. The teen lovers were joined by Biebs' half-siblings Jaxson, 2, and Jazmyn, 4, and clearly had a blast.

Selena seemed to especially enjoy the day at famed Paradise Cove beach.  An only child, she's often talked about wishing she had younger brothers and sisters.

Late last year, she tweeted about being "the happiest girl in the world," in announcing that her mom was pregnant.
