NCIS: Los Angeles has been working hard to hide Daniela Ruah's baby bump from the cameras but the actress says life on set mostly goes on as normal.

The CBS star plays Kensi Blye on the fast-paced drama with Chris O'Donnell (G Callen), LL Cool J (Sam Hanna), and Eric Christian Olsen (Marty Deeks). Although her character is not pregnant, Ruah is currently expecting a baby boy with fiancée David Olsen, brother and stunt double of costar Eric Olsen.

"It's been awesome," Ruah told ET of filming while pregnant. "Everybody has been really accommodating. I think I've also been lucky that it hasn't been a difficult pregnancy at all. I don't need to sit down every two minutes, and I'm not suffering with morning sickness or anything like that. So it's been pretty easy physically for me."

However, NCIS: LA is a stunt heavy program. While camera angles and strategically placed chairs can help trick the audience into thinking Kensi looks no different than any other episode, fight scenes proved to be a little harder on the expectant mother.

"My stunt woman has come in maybe more often than she used to," Ruah explained to ET. "But I need her. There are things that I'm like 'I'm fine guys, I can do this. I can totally jump over the car,' and they're just like 'No. We can't let you do that.'... I think I want to do more than I am allowed to."

NCIS: LA fans need not worry about one of the program's mainstays disappearing for several episodes, however. Ruah shot scenes from seven episodes with executive producer John Peter Kousakis back in October, ensuring that there will still be plenty of Kensi on screen while she welcomes a new addition to her family.

NCIS: LA airs Tuesdays at 9 p.m. on CBS. Check out a promo for next week's episode, "Fallout," by clicking the video below.
