The 57-year-old matriarch has already claimed possession of one of the rooms at the couple's refurbished Calabasas home so that she can stay over when she likes and has even joked about moving in with them and their 19-month-old daughter, North.
A source told the HollywoodLife.com: ''Jokingly, Kris mentioned moving in with Kim and Kanye. She has seen the property with them on several occasions and already claimed one of the bedrooms! She even peed in one of the bathrooms to mark her territory. But she'd never flat out ask to move in.
''She doesn't want to appear needy, but if she had it her way, she'd sell her estate and move right in with them.''
The 'Keeping Up With the Kardashians' star - who split from her husband Bruce Jenner in October 2013 - is reportedly ''dreading'' the day Kim, Kanye and North move out of her home, which they have been sharing with her while they wait for building works on their mansion to be finished off, and is worried she'll be lonely.
The source added: ''You would think Kris would be jumping for joy to have her house back to herself, but it's the opposite. Everyone will soon be out and Kris is dreading that day.''
Kris also has grown-up children Kourtney, 35, Khloe, 30, Rob, 28, from her first marriage with the late Robert Kardashian, and Kendall, 18, and Kylie, 17, with Bruce.
Ahead of their upcoming tour, and prior to the release of their long awaited album, Smoke Fairies played a great warm-up gig at Elsewhere in Margate.
