Kris Jenner hates being called ''grandma''.

Although the chat show host loves her three grandkids, her daughter Kim Kardashian's newborn baby North with Kanye West, and Mason, three, and 12-month-old Penelope - whose parents are Kourtney Kardashian and Scott Disick - Kris has asked the kids not to call her grandma.

Kris, 57, said: ''They call me Lovey and Bruce [Jenner, Kris' husband] is Grandpa. At first I was Grandma and all of a sudden I didn't like the way that sounded. My mom had a friend named Lovey. I thought that was the cutest name.''

Kris and Bruce have recently taken to living in separate houses on some days, sparking speculation their marriage could be going through a rocky patch.

But the businesswoman - who manages the careers of her kids - insists their 22-year marriage is still going strong and the reason Bruce goes to the property is to enjoy the beach.

She told People magazine: ''It's a pretty fabulous relationship. We were lucky enough to get a place by the beach. He spends time there back and forth. We all do. I don't have a crystal ball but I hope we'll be old and grey together.''
