Appeared on: Big Brother 17
This nightlife coordinator from Los Angeles brings something unique to The Challenge: her identical twin sister Liz. Together, the two made major waves on Big Brother 17 by taking turns pretending to be one houseguest. This time around, they’ll be playing individually, but given their past escapades, who knows what sort of mind games Julia and Liz may try to play on their competition? She’s also not one to shy away from romance, it's anyone's bet what she’ll find waiting for her in the Challenge House.
