Nicolas Cage and his wife Alice Kim have separated.

Nicolas and Alice met in 2004, when she was just 19 and working as a waitress at a Los Angeles restaurant, and got engaged two months later. They would have celebrated their 12th wedding anniversary in August.

The 52-year-old actor was previously married to Lisa Marie Presley for almost four months in 2002 and to Patricia Arquette from 1995 to 2001.

He also has a 25-year-old son, Weston, from a previous relationship with model Christina Fulton.

There is a 20-year age-gap between the pair and Nicolas previously revealed his Korean mother-in-law was unimpressed when she first met him.

He said: "When my mother-in-law came to the house for the first time, before even hello or nice to meet you, all I got was, 'She's too young!' And so I knew this was going to be an uphill battle."

Nicolas added that he "made a clear decision" to marry into another culture, saying: "I made a very clear decision to marry out of my own zip code. I mean, way out of my own zip code. I married into another culture, and it's interesting because in Korea they call me the Son-in-Law."

He revealed the couple's wedding was pushed forward so that Alice could travel with him to South Africa while he was making 'Lord Of War', explaining: "You can connect the dots... and we did it because we loved each other."
