Milo Ventimiglia has been "mindful" of safety issues since returning to work.
The 43-year-old actor has adopted a safety-conscious approach since he started filming season five of the NBC drama 'This Is Us', which also stars Mandy Moore.
Speaking about the impact of the coronavirus pandemic on the show, Milo explained: "Mandy and I were inches away on Saturday doing a few scenes together.
"She’s regularly tested, I’m regularly tested. Because of the seriousness of Covid and knowing that Mandy’s pregnant - and we have 150 souls on our crew - nobody wants to put them at risk."
Mandy, 36, announced her pregnancy news back in September, revealing she's expecting her first child with her husband Taylor Goldsmith.
But Milo doesn't stress about working with Mandy on-set because they've built a strong bond with each other.
The actor - who plays Jack Pearson on the show - told Us Weekly: "I trust Mandy and how she goes about her life away from work, and I think Mandy trusts me for how I go about my life away from work.
"We’re always mindful of that. But no, you’re not going to see a Jack dummy or a Rebecca dummy - or Mandy kissing the Jack dummy or Milo kissing them Mandy dummy. It’s not gonna be that!"
Milo also admitted he was excited to return to work following the lockdown, even though he knew the dynamic would be different.
He said: "I was ready to get back, but I was ready to get back safely. I was willing to do my part to stay safe, to keep others safe. I think that’s the biggest thing.
"I think [it’s about] being responsible. I was, like, out in the world, and I was driving and doing everything, but I had to do it all safely - and not for me. I know how to be safe for me. How do I be safe for other people? That’s the big message."
