But as Bravo fans know, it's never just the Housewife who gets camera time; her family life is also closely documented on the reality series. And husband Ashton Kutcher wants no part of it.
Speaking to Andrea Savage on a recent episode of her "A Grown-Up Woman" podcast, the "Bad Moms" star said, "I did ask my husband once. I was like, 'Listen, later in like 20 years, 30 years, what do you think of me going on 'Real Housewives of Beverly Hills'? I'm like, 'Just for like a year!'"
"He was like, 'I would kill you,'" she went on. "I was like, 'Uh, I think that's the appropriate answer.'"
Still, that doesn't mean the actress couldn't have a little hypothetical fun with the franchise! She went on to play a game of "Make Love, Marry, Murder," featuring the husbands of her potential future co-stars, and she held nothing back.
Andrea started to give Mila some choices, opting first to name Dorit Kemlsey's husband, Paul Kemsley (PK). "What are your initial thoughts?" the host asked her guest, who instantly blurted out, "Murder."
"But I don't wanna offend them!" she quickly followed up. "They all seem very lovely, but in this game, I have to kill. He's dead to me."
When Andrea named Lisa Rinna's husband, Harry Hamlin, Kunis shouted, "Oh! You know what? He seems lovely and likes to camp. And I like to camp."
Savage then named Kyle Richards' other half, Mauricio Umanksy, who for years has been voted hottest househusband across the board by Bravo fans.
"Okay," Kunis replied, "so we're still gonna murder Paul. I guess I would marry Mauricio and f--k Harry Hamlin."
Justifying her answer, she explained, "Mauricio, I feel like you can go to Mexico, you can go swimming in the ocean, he seems like he's got some Latin heat."
"So Paul's just murder?" Andrea pressed. Mila did not waver: "Yeah, yeah. For sure."
"But this is where I offend Dorit and Paul, because they're clearly listening to this podcast," she quipped. "They seem like a lovely couple! But in this game, again, [I didn't have a choice.] So he's dead. Dead. But hopefully like a painless death? Like instant death! So no suffering. I'm still gonna marry Mauricio."
When Andrea noted she didn't feel Harry was a good fit for Mila "for long term," the actress agreed, adding, "But for one night, could be kinda fun!"
Flipping the script, Savage asked Kunis to play the game with the wives.
Stumbling over her words, Mila chuckled, "I would murder Dorit. She seems very high-maintenance, and she would be really expensive to get married to. I feel like that's a lot of money, and you know, we're on a budget! So off with her head. She's done." By this point, she was full-blown belly-laughing, as was Andrea.
"I think that I would marry Lisa Rinna, maybe? Because I feel like she would be... Well, Kyle's pretty fun, though. I gotta tell ya," the actress added, pausing to rethink her answer. "I would marry Kyle and then I would have fun with Lisa Rinna... I feel like Lisa Rinna's a little more feisty! She would be really fun for a night."
Mila also said she wouldn't rule out being "a third wheel with" Kyle and Mauricio. "Like, if they were like, 'Come to dinner,' I'd be like, 'Cool!'" she explained, before going into a story about how she was once seated in front of them on a Southwest flight.
"I was so excited," she gushed. "We didn't talk. They were with their kids, and they were doing crossword puzzles, just being like cool parents. And all kidding aside, I was like, 'Oh my God, look at them being real parents!' I was so impressed, to this day, at how normal they were on this Southwest flight with their kids doing crossword puzzles. It was dope! I don't even know if they were aware of this."
