PHOTOS: ‘Orange Is The New Black’ ‘Family’ Vacation — Pen Pal Pics!

It was a real breakout over the holidays for the cast of "Orange Is The New Black" — the hit Netflix series that takes place in a women's prison! It looks like some cast members were out to do some serious bonding, with (from left to right) Adrienne C. Moore, Taylor Schilling, Yael Stone, and Uzo Aduba all getting together in Hawaii.

In their television show, the women are constantly changing allegiances as gangs form in their prison. In real life, however, this looks to be a real gang of gals getting together. That includes Yael Stone fitting right in as the sole Australian actress in the cast — with her character of Lorna Morella currently one of the favorite characters on the show.

Taylor Schilling (above) needs to spend as much time as she can with her cast members, too. She's constantly rumored to be written out of the show where she's a star, thanks to a sprawling cast of fan favorites — with her own character often considered to be a drag on the plots. Taylor has still embraced one big part of the show, though. The actress used to be known as straight, but followed up several sexy "OITNB" lesbian sex scenes by coming out in a relationship with actress Carrie Brownstein.

There's already a lot of buzz over which characters will be leaving the show's fictional Litchfield Penitentiary. That could also include former "That '70s Show" star Laura Prepon, who plays Taylor's onscreen lover. But as these pics show, any changes to "Orange Is The New Black" are really going to break up a loyal prison gang!
