Mila Kunis enjoys low-key lunch in LA after revealing secret to Ashton Kutcher marriage

Mila Kunis showed off her casual fall style as she stepped out for a lowkey lunch with her close pal in Los Angeles on Thursday.

The That '70s Show alum, 41 - who recently enjoyed date night with husband Ashton Kutcher - was seen stopping by celebrity hotspot and private club, Soho House, for the daytime excursion.

The actress dressed down wearing a pair of black trousers as well as a plain, black sweater that had a V-neck cut on the front.

She additionally slipped into a pair of white sneakers and allowed her dark locks to flow down naturally past her shoulders.

A mini, cross-body bag was placed over her right shoulder to hold her phone while strolling along a sidewalk in the city.

Kunis opted for minimal accessories, and added a pair of small earrings as well as bracelets and a watch on her left wrist.

Mila and her friend were seen holding a lighthearted conversation as they headed to the hotspot to grab a bite to eat.

The Black Swan actress has been keeping busy and stepped out for a romantic date night with her husband, Ashton Kutcher, in West Hollywood last week.

The couple enjoyed a tasty meal at the French restaurant called, Marvin, but opted to not use valet. Instead, the stars were seen parking on the side of a busy street next to a meter for the evening.

Mila was stylishly casual in a black and white-striped shirt as well as a pair of loose-fitting, black pants.

The No Strings Attached actor opted for a pair of light blue jeans as well as a white shirt and dark blue blazer.

Kunis and Kutcher tied the knot nearly a decade earlier in 2015 and share daughter Wyatt, 10, and son Dimitri, seven.

Earlier this month, Mila opened up about her relationship with Ashton and also revealed the secret to their long-lasting marriage.

During an interview with E! News , she stated, 'I still feel like we're young and we feel very young. I think that's where the spark is. We laugh at everything.'

In regards to 10 years of marriage, the Family Guy star further expressed that 'It's only 10 years.'

'It's not really that long. I look at my parents, and they've been together for 50. That's long,' Kunis added.

Last month in September, rumors that Mila and Ashton had split following Diddy's arrest began to circulate. However, the speculation was soon slammed as 'ridiculous and false.'

Following the rapper's arrest, resurfaced footage showed Kutcher talking about the disgraced music artist's parties.

However, a source told People that the rumors were 'false' while another insider stated, 'Ashton has no involvement in any of this. He doesn't belong in this conversation about Diddy.'

'Ashton has only seen Diddy in a handful of social and business events, all of which have been documented by the media.'

Kunis is also preparing for the release of her latest comedic drama titled, Goodrich, which is set to premiere in theaters on October 18.

The film also stars Michael Keaton, Carmen Ejogo, Michael Urie, Andie MacDowell, Kevin Pollak and Vivien Lyra Blair.

The premise is: 'Andy Goodrich's life is upended when his wife enters a rehab program, leaving him on his own with their young kids.'

'Goodrich leans on his daughter from his first marriage, Grace, as he ultimately evolves into the father Grace never had,' per an official IMDB synopsis.

The upcoming movie was both written and directed by Hallie Meyers-Shyer, who is known for other projects such as Home Again (2017) starring Reese Witherspoon.

Mila opened up about taking on a role in Goodrich and expressed that the script had been a big inspiration.

'Hallie's writing was so honest and genuine and never felt forced,' she expressed, per ABC News.

'It never felt fake and never felt anything other than the story of these people. Everything made sense. The dynamic was real. The relationships felt real.'

Kunis also talked about the movie hitting theaters rather than releasing on a streaming site.

'It's sad that we're even talking about the fact that it's coming out in theaters. "A movie in theaters, isn't that a miracle?" What a time to be living in that that's like a "congratulations."'

Earlier this month, Mila glammed up to attend the Los Angeles premiere of Goodrich and was joined by other celebrities, such as her co-star, Michael Keaton.

The beauty put on a leggy display wearing a long-sleeved, white dress that contained a hem that stopped a few inches above her knees.

The star slipped into a pair of closed-toed, black heels that offered a bit of color contrast to the look.

Her hair was pulled back into a sleek up do, preventing any loose strands from falling onto her face.

And most recently on Wednesday, Mila joined Hallie Meyers-Shyer and her filmmaker mother, Nancy Meyers, at a special screening of Goodrich at the Aero Theater in Santa Monica.
