Olivia Wilde has opened up about how happy she is over the changes she's experienced since becoming pregnant.

The Rush actress told Lucky magazine that she was enjoying seeing how her body changed, as well as her attitude to other people.

According to E! she said: "I just thought, oh I'm going to hide this forever. But I ended up getting kind of excited to show the bump, as a badge of pride. Like 'I'm a woman! Look at me making a human! I am a goddess!'"

Olivia, who is expecting her first child with Jason Sudeikis, said of her body: "I'm like, double d, hello! I've never been in this section of the bra store! I've been flat chested my whole life, so it's a wonderful new world."

She added: " Pregnancy does shed away all of the b*******. It gives you more empathy because you look at everyone and you think, you were a baby! Pregnancy brings you into this sort of commune - you feel connected to women in a way that you never have."

Talking about the baby, she continued: "He's moving around in there and no one else can tell - it's a little secret friendship."

Olivia admitted that her relationship with fiance Jason wasn't "peaches and cream every day", but said that everything between them was good.

She said of their wedding: "It's certainly not something I feel pressured to do before we have the baby. I'm such a believer in marriage and I think of him as my husband anyway."
