Pauley Perrette just confirmed the rumors that she's leaving "NCIS" on Wednesday morning. The actress announced via a Twitter post that she is finally departing the long-time running CBS Series after having been a part of it for 15 seasons. She also explained her side, in that it was already her decision last year to leave the show.

She also cleared up the speculations that her departure has long been planned and it's not because of an existent rift between her, the network, and the castmates.

Forensic specialist Abby Sciuto

While Perrette confirmed the news about her departure, her fans will always remember her as the forensic specialist Abby Sciuto in the "NCIS" series.

She first portrayed her character role back in 2003. She was also one of three original cast members who had worked closely with the executive producers Mark Harmon and David McCallum.

According to the Hollywood Reporter, the actress was considered as one of the most valued cast members in the "NCIS" series for the past 15 years. In an official statement released by the CBS network, they said, "While it's never easy saying goodbye to a beloved actress and character, we respect her decision to leave at the end of the season. We are grateful to Pauley for all her contributions."

She brought incredible passion to her role

Perrette was known for having an incredible passion for her role as Sciuto.

Since becoming a series regular on the drama, her role has placed her on the map, Variety reported.

In addition to her work on "NCIS," the enigmatic actress has been involved in a number of other television projects. Those include "The Drew Carey Show," "Jesse," "That's Life," "Frasier," and "Murder One." This likely won't be her swan song on television either.

Special send-off

Following Perrette's big announcement, it was learned that CBS is already planning to give her a special send-off celebration. George Schenck and Frank Cardea, current "NCIS" executive producers, revealed that the actress has already brought clarity to her role since day one.

She was a character which inspired millions of fans around the world. Despite her leaving, Perrette will always be part of the "NCIS" family. The drama just started its 15th season and it will be the last season for the actress to portray her role.
