The channel which brought us the Kardashians and its spin-off I Am Cait is also unleashing another Hollywood clan on the world tonight.
Stewarts and Hamiltons might have you wondering the same thing when you first encountered the Kim, Kris and co: who are these people?
Well, George Hamilton,75, is the film and television actor better known for his perma-tan and playboy life than anything he starred in. He was once married to former actor-model Alana Hamilton who became Alana Stewart with her subsequent marriage to Rod Stewart.
George and Alana had one son, Ashley Hamilton, who became an actor and, like his dad, better known for his extramural activities - he briefly married 90210 star Shannen Doherty in 1993; he co-wrote songs with Robbie Williams; he had problems with drink, drugs and eating disorders. He's reinventing himself as a singer-songwriter with an EP out to coincide with the show.
Alana had two kids with Rod Stewart - Kimberly and Sean, who appear in the series. Both have done their bit to keep the tabloids happy in their time too.
Sean dated Real Housewives Of Beverly Hills star Adrienne Maloof, who was almost 20 years his senior, which at least reversed the pattern of his father's love life and his mother's first husband.
