Pauley Perrette Loves Portraying Abby On 'NCIS'

Pauley Perrette, Sean Murray, Emily Wickersham and Brian Dietzen have all given some insight into the last few days on set of the hit CBS series.

He said "Jimmy droughts" happen and this would be one of them.

The following day, Wickersham shared a photo from set of the show that she received from either her co-star Weatherly or fellow actor Simon Rex who looks like he'll be in an upcoming episode since he was on set. In the photo, an adorable dog is photo bombing Weatherly and Rex. Wicker sham called the photo a "gem".

Then, on Friday, there was a lot going on at the set for NCIS.

Perrette's high school friend came to visit her so she took him on set. She revealed they "forgot to take a pic!"

She did however share a photo of them together from their high school prom!

Wickersham and Weatherly goofed around on set as she snapped a photo of him holding up a photo of himself. She called it "Double @M_Weatherly" and wished everyone a "Happy Friday!"

Lastly, Murray revealed his onscreen girlfriend is back! Margo Harshman plays Delilah and hasn't been on NCIS since last season, but it appears as though she's back on set filming since Murray snapped a photo with her. He even called her "one of the coolest people ever."

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