'We tested a lot of gentlemen who were bigger, and I get it — people think the authenticity is kind of ruined by that. 

'But Chris has been heavier, so I think he understands the plight of being overweight,' the actress explained.

'Also he was just the best man for the job. And people wear prosthetics all the time -it’s just weight as opposed to, like, a nose or a chin,' she continued.

'It’s just kind of the name of the game.'

In fact Chrissy had to wear extra padding herself when she landed a recurring role as 'fat lady' Ima Barbara Wiggles on American Horror Story: Freak Show in 2014 and 2015.

The star told People: 'It was sobering. I thought, "What if I become that heavy and can’t walk around or get stuck in the doorframe?" I was like, I don’t want this for me.'

Meanwhile, Chrissy chatted about This Is Us to Wendy Williams on her  show on Friday.

Wearing a black and white-striped T-shirt under a black silky smock, she dished about her new beau, Josh Stancil, who is a camera grip on the show.

They've been together for five months and Chrissy revealed that Josh was okay about shooting bedroom scenes between her and Chris.

'But it wasn't his favorite thing when I had a long kiss with Chris and we had to do it, like, 12 times,' she joked.
