"It sucked because [show creator] Jenji Kohan and I wanted me to be in it more, but with the schedule, it didn't happen," Prepon told Us Weekly on Thursday. "I was so bummed out. But I handled it, so I'm in every [episode] in season three. It is so good."
Prepon, formerly of That 70's Show, plays snarky, tattooed inmate Alex Vause, who has a complicated history with Taylor Schilling's character, Piper Chapman.
The 34-year-old actress previewed season three episode titles in an Instagram post last May.
"It's official!! Season 3!! #oitnb #alexvause #backtothebighouse," she wrote.
