Ruby Rose says Orange Is The New Black will be "the sexiest season by far."

The Netflix prison drama debuts all 14 episodes of Season three this Friday, and in a featurette the Australian actor and her burdensome "genetic perfection" are on show.

The 29-year-old plays new inmate Stella, who goes after main character Piper (Taylor Schilling), creating trouble for her on-again, off-again girlfriend Alex (Laura Prepon).

The promo shows the new love triangle between the ladies of Litchfield Penitentiary, with Stella flirting with Piper, and Alex looking worried.

"Stella definitely does shake things up," Prepon said.

"She's cocky, she's flirty and she's super funny," Rose said.

"This is the sexiest season by far."

Rose will make her debut in the series when season three is released on Netflix on June 12.
