Ruby

 was a housemate on Summer of Secrets. She placed sixteenth.

Coming in as a Celebrity VIP on Day 3 with Troy, Ruby secretly nominated during Week 2, and voted to fail her housemates on the VIP Treatment shopping task, placing them all on a limited food budget for the week. In Week 3, she was announced to be an official housemate, but got ejected shortly after, because of her failure to submit nominations during her first official week as a housemate.

Ruby and Troy are the first housemates in JBBUK history to enter the game after launch night.
