Los Angeles: Actress Olivia Wilde, who has 10-month-old son Otis with her partner Jason Sudeikis, says pregnancy is a 'terrifying' experience, but she recommends it.

She even compared her enormous belly to a horror movie.

"I was doing re-shoots for this movie...(at) eight and a half months pregnant and I was just so excited to be working that I was like, 'I'm gonna act the f**k out of this scene. I was so happy, I was like, 'Here I go. Still got it'," she said on "The Daily Show with Jon Stewart" while speaking about her new film "The Lazarus Effect", reports femalefirst.co.uk.

"And the reason it's kind of framed oddly is because there's just this enormous belly, which is a whole other horror movie. I mean, the look of it... (Being pregnant) is really insane and terrifying. I recommend it," she added.

Wilde is keen on having another two children as both she and her partner Sudeikis are one of three siblings, but she is waiting to make sure she can "keep one alive" first before getting pregnant again.

When asked if they'd be adding to their family, she said: "I'm part of three, he's part of three. I like the idea of that but if I can keep one alive, I'll be really proud of myself."
