Cameron is 78-year-old Michael's only child with his first wife Diandra Luker; the former couple were married from 1977 until 1995. He has two half-siblings – Dylan Michael, 20, and Carys Zeta, 17, from Michael's marriage to Catherine.
Cameron was previously sentenced to five years in prison for drug-related offences in 2010, but his term was extended further after he admitted to smuggling drugs into jail. He was placed in solitary confinement from 2012 until 2014 and was released to a halfway house in August 2016.

In an eye-opening interview with The Telegraph, Catherine, 53, explained how their relationship is far from perfect. She admitted: "It's impossible for there not to be ups and downs if you live with the same person and wake up with them every day."
She went on to say: "I've been waking up to Mike for nearly 25 years. I love being married but it's a crazy thing when you really think about it. Will you marry me? Sure! But then you think about the Chanel purse you spent a fortune on, and actually I don't really like it any more – I'll put it up for resale."
