"NCIS" season 12 is one week away from going on the floors, however the cast is already thrilled to reunite for the new season. Much recently, the "NCIS" cast got together to celebrate the dual birthdays of Michael Weatherly (Tony DiNozzo) and Rocky Carroll (Leon Vance) on 8 July.

Pauley Perrette who plays the role of Abby Sciuto on the CBS' show posted a picture with birthday boys along with fellow co-stars Emily Wickersham (Ellie Bishop) and Brian Dietzen (Jimmy Palmer).

"Had an #NCIS very happy @M_Weatherly and @RockyCOfficial birthday today!" she captioned the photo posted on her Twitter account.

Even Dietzen took the opportunity to share the photos from the birthday celebration.

"Spent the day celebrating the births of two of my favorite people, @M_Weatherly and @RockyCOfficial !! Send them some birthday love!!", he tweeted.

The cast and crew of "NICS" would soon get together for the first script reading session, as per the reports. Previously, it was also understood that the shooting of "NCIS" season 12 has already kicked off. But Dietzen played down the reports.

When a fan tweeted on Dietzen's Twitter account sharing his excitement for the beginning of "NCIS" season 12 shoot, he replied saying that, "Not quite yet! We start filming after our table read next week. I'll be sure to tweet out a pic or two!"

Meanwhile, there has been lots of demand for bringing Cote De Pablo back to season 12. Fans want Pablo, who played Ziva David in one of the episodes of season 11, to reunite with actress Emily Wickersham's character in season 12.

"Many people have approached me in the recent past, wanting Ziva and Ellie to meet at some point of the storyline, but the situation for such epic meetings needs to be organic. We cannot hope to fake situations and arouse positive emotions at the same time," Gary Glasberg, producer–director of the "NICS" said to Air Herald when asked about his perspective on featuring the Emily-Ziva meet.

Moreover, "NCIS" season 12 is expected to become a huge success and draw a huge amount of audience. For the last five years, "NICS" has been the most watched show in the US. More than 57.6 million people tuned in to watch it in 2013 and the show have recently won the International Television Audience Award in the Drama TV Series category at the 54th Monte-Carlo Television Festival.

"It has been a pleasure working on 'NCIS' so far. I would like to thank the global audience for making it successful," Glasberg said about the success of the show to the website.
