Olivia Munn has frozen "a bunch" of her eggs.

She said: "I turned 35, then you're high risk. I did, years ago, freeze a bunch of eggs. I went to the doctor and did the whole test and he said, 'You know, you actually have a lot of eggs. You're really lucky.'

"A girlfriend of mine -- we're the same age -- she'd gone to the doctor, had a test and she had the egg count of a 50 year old.

"For me, this is the count you'll have until your 30s, even 40s -- you'll always have a lot."

And the 'Mortdecai' actress thinks the practise has become increasingly more common and she believes every woman should freeze their eggs so they don't have to worry about their biological clocks ticking.

Speaking to her friend Anna Faris on her 'Anna Faris is Unqualified' podcast, she said: "I actually started telling my friends about it.

"It's no longer on the experimental list and I think that every girl should do it. For one, you don't have to race the clock any more. You don't have to worry about it, worry about your job or anything. It's there.

"It's also just like, why not do it, because I see so many women who go through this. Doomsday is now like whatevers day, because I am prepared."
