Ashton Kutcher learned to value his privacy ''the hard way''.
The 'Two and a Half Men' actor is desperate to keep his new romance with former 'That '70s Show' co-star Mila Kunis private following his high-profile marriage to, and split from, actress Demi Moore.
In an interview with ELLE magazine, the actor said: ''You know, I've learned the hard way how valuable privacy is. And I've learned that there are a lot of things in your life that really benefit from being private. And relationships are one of them. And I am going to do everything in my power to have this relationship be private.''
The 35-year-old star met Mila, 29, on the set of the hit sitcom - which ran from 1998 to 2006 - in which they played love interests, but their real-life relationship didn't blossom until last year following his split from the 'Charlie's Angels: Full Throttle' actress.
Quizzed about their transition from co-stars to couple, he responded: ''People will fill in the blanks however they want.''
Ashton, who joined 'Two and a Half Men' in 2011 following Charlie Sheen's departure from the show amidst a public feud with creator Chuck Lorre, added that people perceive him to be a demanding Hollywood star but he insists he's really ''just a geek''.
Speaking on his initial meeting with Chuck, he said: ''There was an impression that I was this sort of larger-than-life, with-a-posse kind of guy. After we met and hung out, he realised I was just a geek.''
