She can be famously frosty when it comes to being interviewed.

But actress Mila Kunis certainly warmed up when she spoke to W Magazine, and posed for an accompanying '60s-inspired photoshoot for their latest issue.

Opening up about her private life with fiancé Ashton Kutcer, the 30-year-old actress - who is pregnant with her first child - confessed that she may put her acting career on hold for family life.

"I'm sure Meryl Streep has a very different point of view. But I'm excited about being a full-time mum," she told the publication.

However, it doesn't look as though Kunis and Kutcher, 36, will be welcoming the world to their wedding anytime soon, as the pair are planning a very small affair ... without any guests.

"I never wanted to get married," she tells W. "Now my theory on weddings is: don't invite anyone.

Do it privately and secretly. My parents are okay with that. They're just excited that I said yes."

However, that didn't stop Kunis from attending a huge wedding at the weekend, which saw Google's Nikesh Aror marry entrepreneur Ayesha Thapar in Italy.

Kunis and Kutcher donned traditional Indian attire for the ceremony that was held over a number of days.

Meanwhile, the Black Swan actress also spoke about how starring on That '70s Show was the perfect build up to finally falling for her co-star Ashton, who she describes as her "movie star crush".

"My first real kiss ever was with him on the show," she says, adding: "And when That '70s Show had a prom, my date for the prom turned out to be my fiancé. We can honestly say that we went to prom together!

"I went through everything embarrassing that a girl can go through in front of my fiancé. There's no question that he's seen the worst. I find that comforting."

Still, at times during the interview her sometimes surly attitude shines though.

On That '70s Show she says, "I will never wear bellbottoms again," while on Black Swan she adds, "I will never dance again".

Just last month, Kunis gave one of her most awkward interviews yet as she got defensive when speaking to The Star Ledger reporter Stephen Whitty.

When asked, "How are you feeling?" Mila answered: "I don't talk about that for publication."

She also took issue with the reporter's suggestion that she is looking for more "independent" film roles, after filming Blood Ties, Third Person and The Angriest Man In Brooklyn back-to-back.

"Not really, because in the middle of all that I still did Oz (the Great and Powerful) and I still did Jupiter Ascending, so that sort of destroys your assumption," she snapped.

Cutting him off mid-sentence, Kunis then said: "I know what your next question is so let's just skip it. You're going to ask me what I think about what's going on now in Ukraine.

"Just because I lived there until I was seven doesn't mean I identify with Ukraine."
