Ashton Kutcher Talks About Having Sex with Mila Kunis, Their 'Beautiful' Baby and … Brad Pitt

Ashton Kutcher might have been 7,500 miles away from his fiancée and daughter but they were uppermost in his mind on Friday. 

The Two and a Half Men star was at the Tech My Way conference in Sydney, Australia, to talk about his tech partnership with Lenovo, but the new dad couldn't help discussing his baby mama, Mila Kunis. 

"I get to have sex with her, it's amazing," Kutcher, 37, said while talking about a morning hike he took with her and their daughter, Wyatt Isabelle. 

"She's beautiful," he said of his 4-month-old. "This kid – I'm freaking out… It's new but it never gets old." 

Almost as if on cue, a baby began crying as he talked about his conversation with Kunis following a recent press junket for her film Jupiter Ascending. His reaction was immediate. 

"It's okay, baby, it's okay," he said as he put his hand to his chest. "That's like a flash[back] – I want to go home … Let the baby cry, I'm used to it. It's fine." 

Kutcher was using his story to illustrate his point about someone once telling him there are no dumb questions. But explained that he was startled at some of the basic enquiries reporters made during Kunis's interviews. Questions like "What dress are you wearing?" "I prize her as the most valuable person in the world to me," he said. "You have a chance to sit with Mila Kunis and that's what you ask her?" 

Kutcher then revealed that one of the questions he's often asked is, "What's Brad Pitt like?" 

"He awesome. He's amazing," Kutcher told the audience. "I walked into a room and it looked like he had lights that were just built for him. It was a regular room, but it was like his hair … it was like a wind machine [blowing back his hair] but there was no wind. It's just Brad Pitt being sexy. And brilliant. Hate that guy. Love him. Hate him." 

Later in his 25-minute speech Kutcher pulled out his cell phone and read out emails he'd gotten from some of his celebrity friends after he asked for their best piece of advice. 

From Kunis: "Don't let your ego get in the way of asking for help." 

From Taylor Swift: "Keep your hopes high and your expectations low. You are not entitled to anything but there is nothing that you can't earn. And most importantly, enthusiasm can protect you from absolutely anything." 

He then shared an email from Bradley Cooper: "Hey pal, thanks for asking. You know often I thought about this old cartoon commercial when I was a kid that sent the message to 'Be yourself.' And just how vital that is to growth. And when I finally realized that notion, some 30 years after watching those commercials between Saturday cartoons, I found a true difference in my daily life. Knowing that we all have ourselves and all we have is ourselves – our uniqueness – that is what we can use to cultivate in order to create or do whatever it is that we want to do in this life." 

Chris Rock had two important points to make: "1. People that can't listen can't lead. 2. One of the keys to success is the ability to listen to people that you know you are smarter than." 

And Kutcher then offered his own take: "The number one piece of advice I ever received is that there is no substitution for hard work," he said. "The second thing: Being smart is incredibly sexy." The third thing, said Kutcher, is the importance of generosity. "Is it good for you, is it good for me and is it good for the greater good?"
