"Early Show" co-anchor Maggie Rodriguez reported casting directors are now taking a new look at actors with natural faces and bodies - not those smoothed, plumped and filled by plastic surgeons.
US Weekly's senior editor Bradley Jacobs said the trend is making its way into the business because casting directors are seeing young women who don't look like young women.
"They've got filler in their lips. Their foreheads don't move, and they're saying, like, 'I'm not casting a reality show, I'm actually casting a movie, and you're supposed to look like a 23-year-old girl, but you don't.'"
Psychologist Dr. Jennifer Hartstein said TV shows, such as "Mad Men," which feature naturally curvy women, are having an effect on the business.
"Women are women in ('Mad Men'), and there's a real appreciation of that," Hartstein said. "Christina Hendricks (who plays Joan Holloway on 'Mad Men') is a curvy woman who embraces her femininity, who embraces her body and some of the fashion houses are looking at more curvy women and appreciating that, which I think the real woman in the real world is much more like."
She added, "We aren't clothes hangers."
"Early Show" co-anchor Maggie Rodriguez pointed out that some actresses, such as Keira Knightley and Natalie Portman, have probably had more successful careers looking naturally than women who have had plastic surgery.
Jacobs agreed, saying, "They do fine work. They're in period dramas. They're in real movies. And what you see more and more in entertainment these days are those disposable reality shows and movies that are made so quickly these days, but especially reality shows. They just pump out newer celebrities and there's a lot of surgery going on in that world."
And in that world is Heidi Montag, who famously received 10 plastic surgery operations in one day. Jacobs said Montag revealed it all on the reality show "The Hills" premiere.
Jacobs said Montag said she felt pressure from the business.
Jacobs said, "She wants to be an actress. She wants to be a singer, work in the business. In her mind, she needed to look a certain way - kind of like a Barbie."
But Hartstein said there are plenty of other actresses in Hollywood who are a standard for natural beauty.
Kate Winslet, she said, is among them.
"What a great aspiration for young people to say, 'Oh, that's what I can go to by just taking care of myself."
Rodriguez pointed out other timeless beauties include Meryl Streep and Julia Roberts.
She said, "Maybe it pays to be natural."
"It might," Hartstein replied.
Jacobs added, "What's interesting is, for women who are a little bit older, maybe 40 plus working in the business, people sort of do expect them to get a little work done, but it needs to not be obvious. We need to not be able to tell, so there's a difference between good plastic surgery and bad plastic surgery once you get past a certain age."
