'Orange is the New Black' fans are eagerly waiting for the comedy television drama to return to the small screen next year. While neither Netflix nor the show runners have revealed the exact premiere date of the show's Season 4, the opening episode of the new installment is expected to be aired in June 2016.

Christian Today reports that there are several rumors online about the plot of the upcoming season of 'Orange is the New Black' and the most thrilling one so far is that 'I am Cait' star Caitlyn Jenner might have a cameo appearance in the popular television show. In fact, Jenner's firm attitude and advocacy on LGBTQ rights can definitely give the series an even bigger boost.

Meanwhile, OK Magazine reported that a source told them, "It's the perfect time for Caitlyn to come in and help Sophia take a stand against the bullies. Plus, with Cait's popularity, she'd surely draw more viewers."

One plot detail of 'Orange is the New Black' Season 4 that is worth talking about is that Litchfield Prison will be facing an overcrowding problem. In fact, the prison will turn out to be a hotbed for clash among old timers and the new arrivals. This was actually evident in the closing episodes of the last season. At the same time, the living condition in the prison will also become more difficult, hinted Kate Mulgrew, who portrays the character of Red in the series.

Moreover, Suzanne Warren aka Crazy Eyes, portrayed by Uzo Aduba, is also expected to have a meaningful love story in 'Orange is the New Black' Season 4. Talking to TV Guide about this budding romance and what this feels like for her character, Aduba herself revealed this information.

"I think she would be in that space of openness and trying to learn. I think that she would be giving of her heart and her mind and her soul, in complete fullness and complete abandon. And that might be pretty, messy, sticky - but beautiful," Aduba told the website.

As of now, fans of the show are eagerly waiting to see Jenner's rumored cameo appearance, the new inmates and the overcrowding of Litchfield and a budding love story between Warren and Maureen (Emily Althaus) in Season 4 of 'Orange is the New Black.'
