In the article Olivia wrote for Shape magazine, she opened up about the unrealistic expectations that women face after giving birth. She said that she believes in a world where women are "not expected to shed any physical evidence of their child-bearing experience" and added that she does not want to waste any of her time attempting to attain "some subjective definition of perfection."

Olivia, who was once married to Italian prince Tao Ruspoli, is now with "We're the Millers" actor Jason Sudeikis. They started dating in 2011 and has been engaged to marry since January of 2013, but a source revealed to OK! Magazine last year that the couple is in no rush to get hitched.

Olivia has said that she doesn't feel any pressure to get married and knows that the both her and Jason are fully committed to the relationship. According to the source, the couple is extremely happy with the way things currently are.
