Selena Gomez & Jake T. Austin: Sierra Mist Mates

On-screen siblings Selena Gomez and Jake T. Austin stick together as they have a party at the Sierra Mist Beach House on Sunday afternoon (July 26) in Malibu, Calif.

The duo enjoyed a barbeque and played in the pool for hours with Jake‘s mom Gina, lil’ sis Ava as well as good friend Christian Fortune.

Selena tweeted from the beach house, saying, “Just spent 3 hours talking to the sister I’ve never had. :) much better now. Power Ranger is good.”
