Michael Weatherly and Pauley Perrette have been costars on NCIS since 2003 so their friendship has definitely grown over the years.

The entire cast is pretty close actually, always showing support for each other on and off social media.

These two costars decided to celebrate Christmas a little early together.

On Friday night the two had their very own "Xmas dinner" in honor of the holiday season.

Weatherly shared a snap of himself with Perrette as they gleefully smiled at the camera.

The two NCIS stars indulged on sushi and sported yellow smiley face pins. We are not sure what the pins signify, but both made their presence known in the image.

The 47-year-old Weatherly looked a tad more festive than Perrette since he donned an olive green sweater whereas she went with what looks like the black sweater with white hearts on it that she worn on set days ago while filming an episode that Rocky Carroll is directing.

Perhaps their Christmas meal was on set with the rest of the cast and even the crew. No other images from their Christmas dinner have surfaced thus far, but whether it was just the two of them or even more members of the NCIS family included, it looks like it was a great time.

NCIS airs on Tuesdays at 8 p.m. ET on CBS.
