Ashton Kutcher was a guest speaker at the Lenovo Tech My Way Conference in Sydney on Friday. The actor was invited to speak about new tech to audiences, but the conversation made a shift to his life with Mila Kunis.

According to US Weekly, Kutcher began to brag about his life with the actress. "Last week, I was walking with Mila... Kunis, who's my fiancée, It's amazing!" he remarked, "She plays the Queen of Humanity," Kutcher said.

He shifted the conversation to a discussion about Kunis' new movie "Jupiter Ascending." He recalls a point in her press junket when an interviewer asked Kunis what she was wearing and admits that he felt offended on behalf of his fiancée.

He later suggested that the question was a wasted opportunity for the interviewer. "There is such thing as a dumb question," Kutcher remarked.

In later moments, he spoke at some length about fatherhood. He gave an anecdote about a shared moment with his new family. "We were walking, and I had baby Wyatt strapped to me, she's beautiful; it's new. Never gets old," he recounted.

Kutcher admitted that he encountered difficulty planning the speech for the tech event. Kutcher, who is also a product engineer for Lenovo, said. "I really struggled with what I was gonna talk about today; I don't take these opportunities lightly. To be able to stand up in front of people and talk and share how you feel about things is a privilege."

Everyone is aware of Kutcher's sense of humor. His time on TV in shows like "That 70s Show", "Three and a Half Men," and "Punk'd" have cemented him as a comedic actor.

He certainly kept audiences laughing and paying attention at the Lenovo Tech conference.

In addition to discussing his personal life with Kunis, Kutcher's admissions also squashed rumors of their secret wedding. The rumors began when after Kunis appeared on the Ellen Show a few weeks earlier.
