But perhaps they should get their fill while they can, because Roberts revealed she may give up acting completely in the future.
"I think as I get older, there might come a time when I don't want to be in front of the camera anymore and want to be more behind the scenes: I would love to produce and maybe write," she said in the January issue of Allure magazine.
Roberts, 24, continued, "I thought of it a lot during 'Scream Queens' when every morning there's full hair and makeup and heels and mini dresses. And I thought, you know, I kind of want to show up to work one day and not care what I look like. It would be nice to just slip away for a little bit."
The actress said an incident with her 14-year-old sister, Grace, also led her to care less about looks. Roberts recalled when she tried to post a picture of themselves on Instagram, and her sister pleaded with her not to.
"She came up to me and said, 'Please don't post that; people are calling me ugly on your Instagram,'" Roberts said.
The actress said the moment deeply affected her. "I've met some of the most beautiful people in the world, who have been some of the most awful people. I'm getting choked up talking about it," she said. "I thought, here's my little sister, and people are calling her ugly. ... I love her more than anything or anyone in the world."
The incident with her sister is one of the reasons why Roberts decided to pose naturally on the cover of Allure.
"You can put yourself out there and not Photoshop yourself or Facetune yourself," she explained. "It's just fine to say, 'Oh, I looked bad in that picture, but that was such a fun day. ... I also wanted to show people ... [with] my hair down. Basically no makeup."
"I'm a small-B boob," she added. "I can't even fit into Victoria's Secret bras. They're all too big! So I'm standing up for the small-busted girls."
