It was all happening for Amanda Seyfried on set of The Last Word

AMANDA Seyfried fell in love and fell pregnant on set of her latest film. Her ‘psychic’ co-start Shirley MacLaine had a hunch.

HEAVILY pregnant, Amanda Seyfried, 31, is grinning from ear to ear. “I can’t wait to meet my kid,” she tells news.com.au.

“I was born to be a mother. I’ve known that since I was little,” she says.

Engaged and pregnant to Thomas Sadoski, 40, with whom she began a relationship on the set of their upcoming movie, The Last Word, Seyfried explains how it almost didn’t happen.

“The lead actor cancelled five days before the shoot and Tommy (who formerly starred in The Newsroom) was on a list of a couple of guys. And I was like, ‘Come on! This is a no brainier!’” laughs Seyfried.

“And so there I was with him on set. I’ll never forget it. I don’t think my kid will either, even though [he/she] wasn’t there.”

Their co-star Shirley MacLaine (who is also known as a psychic) had a hunch there was a romance brewing. Seyfried laughs, “She said the other night that she was there when the baby was conceived!”

She adds, “It’s so weird and beautiful that I’m sitting here talking about this movie that really meant a lot to me, brought me great joy in the experience, but also brings me great joy in the present, right now.” She pauses.

“It’s a once in a lifetime thing and will be something that we show our kid and say, ‘Look at us! Look at mommy and daddy!’ And Shirley MacLaine!’”

When it comes to her baby’s impending birth, a subject which can make even the most prepared woman nervous, she says, “Oh my God! Four months ago I was in such a state. I thought to myself that I’d rather be pregnant forever because I didn’t want to go through it.

“But if you educate yourself [the anxiety will lessen], and the more information the better. I feel so much relief now about knowing what happens — why, when, how — that I’m now just really excited.”

Currently in her third trimester, like so many women, she’s glad to see an end in sight to her pregnancy. “Yes, that’s what happens. We wouldn’t want to get these babies out if it wasn’t uncomfortable, and so it all makes sense to me. I’m so ready now! All I want to do is start. I really want it to come early because I can’t wait.”

Seyfried is animated, clearly enjoying this time in her life. “The pregnancy has been fine, other than really bad heartburn. For everybody who’s had babies, the second trimester is as though you’re not even pregnant. You just get to hang out and build a human without really feeling all the symptoms, if you’re lucky. But I know people have had difficult pregnancies, and I’m grateful that mine wasn’t.”

Refreshingly, she refuses to succumb to too much pressure about watching her weight gain during the pregnancy. “I can’t feel guilty about not exercising or hiking the way I used to because I’m creating a human. And that’s another thing about being a woman, having the capability of creating everybody,” she says.

“It blows my mind. I just have to remember that there’s no room to feel guilty about any of that other stuff.”

Even though she’s yet to be a mum, she says she’s already changed. “I was always into babies but I wasn’t prepared for the weird switch that happened when I got pregnant. When I hold children now it’s so much more intense. It’s almost like I’m so much more connected to this emotional piece of my heart that I wasn’t familiar with before.

“I think the Buddha said that motherhood is born with the child. I know that there’s so much more in a couple weeks when this baby comes and I’m going to have an experience that I can’t even fathom. And that’s what everybody’s been telling me. And I’m so excited about that.”

She first met Sadoski in 2015 when they starred in the Broadway production of The Way We Get By, and she was formerly linked to actors Dominic Cooper, Josh Hartnett, Ryan Phillippe, Desmond Harrington and Alexander Skarsgard. Sadoski was married for 8-years to actress Kimberly Hope.

As for walking down the aisle, she says, “Yes, we will, but I think that’s just fallen by the wayside for the moment. I think when our kid is walking I’d love to have a wedding at the farm”, referring to a property she purchased three years ago in Stone Ridge, New York.

“I want them to be able to be a part of it in a way that they wouldn’t be in utero,” she smiles. “It’ll be great.”
