Kirsten Dunst was thinking about freezing her eggs before she fell pregnant.

The 'Bring it On' star would have gone down the route of relying on medicine to preserve her fertility until a later date if she hadn't met her ''soul mate'' Jesse Plemons - who she began dating in 2016 - and had their son Ennis in 2018.

Speaking to Net-a-Porter's digital magazine PorterEdit, she said: ''We're about as married as you can get. We have a kid together.

''My mom was like, 'But when are you guys getting married?' And I said, 'Mom, I'm not going to get married when I'm pregnant. I want to have fun and have a drink. I mean, we're paying for this wedding.

''I'm paying for the bar! I want to enjoy it.' [My mom is] kind of old-school in that way. I thought I would have a hard time getting pregnant, but it was a surprise. If I hadn't met Jesse, I would have frozen my eggs. [But] it feels like I lucked out.''

The 37-year-old actress met Jesse, 31, when they were shooting the FX series 'Fargo' in 2015 and she knew almost instantly that he was the one for her.

She explained: ''He's my favourite actor-the best I've ever worked with. I just knew he would be in my life forever. I didn't know what capacity that would be at the time. When the show was over, I just missed him terribly. We didn't get together until a year later. We were both smart enough that we were wondering if the connection was just because we were working together. But it was real.''

And, although they both have careers in acting, Kirsten doesn't want to force her son Ennis to follow in their footsteps and, instead, wants him to do school plays.

She said: ''If you have a kid who's very cute, I get why people do it. Do a Gap ad and you can make your college money. It's the first time I kind of understand it. Ennis is so adorable, with two big dimples.

''He is such a happy baby, and I see why I might want that memento of him at this age, but we will probably just encourage him to do school plays.''
