Taylor Schilling
is officially the big 3-0!

The "Orange is the New Black" star celebrated her milestone birthday with her fellow inmates at Catch Roof restaurant in New York on Saturday.

Natasha Lyonne (Nicky), Laura Prepon (Alex), Uzo Aduba (Crazy Eyes), Samira Wiley (Poussey), Selenis Leyva (Gloria), Kate Mulgrew (Red) and Laverene Cox (Sophia) were all on-hand to sing happy birthday to the blonde beauty. Joshua Jackson was even there too ... random!

The actress also had an "OITNB" themed three-tired cupcake platter from Lily Spots in New York.

Taylor looked gorgeous for the special night, rocking all all-black ensemble, shorts, a quarter-sleeved blouse and black pumps at the party. She styled her blonde tresses in a low bun and wore minimal makeup.

We love that the ladies are super close off the set too -- and LOVE seeing them all made up.
