"We are shooting our final Papa Gibbs episode, and the last #NCIS episode #RalphWaite shot re-airs tonight. #RIP," Perrette also tweeted on April 22.

The season 11 finale will tribute the late Ralph Waite. Waite, a veteran actor whose career spanned over 50 years, died on Feb. 13 at the age of 85. He recurred on the CBS show as the father of Leroy Jethro Gibbs, played by Mark Harmon.

"We've talked about [the episode] since Ralph's passing, and I think we've come up with a really great crime story that will bookend into the passing of Jackson Gibbs," executive producer Gary Glasberg told Entertainment Weekly. "That's going to be a really emotional storyline that Mark Harmon has been involved with since day 1."

The NCIS season 11 finale will air on Tuesday, May 13 at 8/7c.
