If you're a fan of NCIS director Leon Vance, then you're in for a real treat next season. Rocky Carroll revealed he will be appearing on both NCIS and its spin off NCIS: Los Angeles next season, TV Guide reports. And judging from the number of episodes, it won't be a minor gig for the actor.

"I'll be keeping my normal routine on the 'mother ship,' and I'll be doing at least six of the first 13 episodes of NCIS: Los Angeles," Carroll said.

While NCIS' strong performance in the ratings is already a given for most fans, the CBS procedural is also quite formidable force in during rerun season, which recently went underway in June.  CBS recently ranked as the most popular network for the first week of summer, but not because of its original programming, but thanks to reruns from top-rated NCIS and The Mentalist.  This, despite the relatively strong showing of original Fox and ABC shows So You Think You Can Dance and Wipeout.

For the week at hand, CBS averaged 8 million viewers, around 2.5 mil more than runner-up Fox (5.5 mil) and NBC (5.3 mil).  For its part, NCIS has had a strong showing in the ratings since its debut, but it was in season 5 when it became a top 10 program, averaging 15.65 million viewers per episode.  It bucked the trend of decreasing television viewership in season 6, when its ratings showed a slight upgrade in ratings to 17.89, good enough for the TV's fifth spot.

With the seventh season of NCIS not returning until late 2009, on top of that secretly filmed torture scene involving her, TV Guide reports that Ziva, played by Cote De Pablo, doused rumors that the MOSSAD operative will not be returning next season.

NCIS big boss Shane Brennan said that come September when NCIS returns, "all will be revealed and you will be surprised. It will come at you from left field."  In a nutshell, yes, the other half of the Tiva tandem will be back.

Celebrities are finding the downside to the existence of social networking, because it's getting easier to track them down.  But in Pauley Perrette's case, people think it's easy to steal her identity.  The NCIS star has been a victim of impostors, who have been pretending to be her on the websites Twitter and MySpace.  Upon finding out, she took action immediately.

"I am NOT on Twitter.com. I am NOT on MySpace.com," Perrette exclaimed.  She went on to say that she does have a MySpace page for her music but that it doesn't really add anyone as friends.

While the return of NCIS and its seventh season is still a good four months away, Michael Weatherly and Cote de Pablo recently talked to ET Online about their team-up, and how it has further boosted the popularity of the already highly rated show.  Their on-screen chemistry, after all, is one of the reasons why the series is such a hit.

"They want to know how hot [she is], says Weatherly, when asked about the one thing that he is asked most often about his partner.  "I had a guy at the airport and he was all about the Ziva.  He wanted to know if Ziva is dangerous and sexually charged."
