Allure

Katie Holmes is "open" to giving her 6-year-old daughter Suri a sibling one day.

The ex-Mrs. Tom Cruise tells the current issue of Allure magazine that, although there's no man currently in her life, she can envision a time when she might want to expand her family.

"I don't know," she said. "I'm open to it."

Though she doesn't talk directly about her 2012 high-profile divorce from Cruise, she admitted, "A lot of people have gone through a lot of stuff," and said she's hoping for a more "peaceful year for a lot of the people in the world."

"When you look back on the last year, there were a lot of tragedies - Hurricane Sandy, the Connecticut shooting. I … I just hope it's a good year for everyone," she said.

Holmes also played coy about rumors that she may be going to law school.

"Well, my brother and father are attorneys, and - we'll see. I like the practical thinking of attorneys," she told the magazine.

She also talked beauty and fashion with Allure, admitting that she allows Suri to dress herself.

"She's got a great eye, she really does," Holmes said, with a hint of pride.

As for the best beauty advice Holmes ever got, it comes from her mother: "You may be pretty, and you may be talented, but nobody will remember that if you're mean."
