Keeping Up with the Kardashians stars Kris and Bruce Jenner have separated after 22 years of marriage.

The pair released a statement to E! Online: "We are living separately and we are much happier this way.

"But we will always have much love and respect for each other.

"Even though we are separated, we will always remain best friends and, as always, our family will remain our number one priority."

Kris has four children from a previous marriage and Bruce has four plus they have two children together, Kendall and Kylie.

In June, daughter Khloe told The Tonight Show: "They're not having problems, but they still like to live apart, which is definitely different.

"You know, Bruce and my mom, they wanted some... In my house there is a man room for Lamar.

"A room, not a different house. So I think they took my idea and ran with it. They got another house and Bruce stays there sometimes."
