Kris Jenner has ''too much sex''.

The 'Keeping Up With the Kardashians' matriarch has been enjoying a relationship with 34-year-old Corey Gamble but admitted the physical side of their romance has left her ''exhausted''.

She said: ''I literally have too much sex. I'm exhausted.''

Though the 59-year-old star - who has four children from her first marriage to Robert Kardashian and two with second spouse Caitlyn Jenner - and Corey love one another, they are not planning to marry.

Speaking on 'Keeping Up With the Kardashians', she said: ''I've realised I don't want to get married, but I really have a lot of fun with Corey, and I love being with him.

''He said, 'I don't want kids. I love you, and I feel that way about you.' ''

Elsewhere in the series finale, Kris branded Scott Disick a ''piece of s**t'' when pictures emerged of him with his ex-girlfriend.

The furious matriarch slammed the model - who has children Mason, five, Penelope, three, and Reign, nine months, with her daughter Kourtney Kardashian - after photos surfaced of him getting close to Chloe Bartoli.

She raged: ''That piece of s**t!

''It's disrespectful. I think I've often made excuses for Scott, and it's just getting tougher and tougher.''

And though Kourtney felt she was on the ''verge of a nervous breakdown'', she knew it was time to end their nine-year relationship.

She explained: ''When I wake up, I feel sick. I'm just literally on the verge of, like, a mental breakdown....

''I can't do it anymore. My mind is completely made up. Yeah, no, I mean, I told him that. God just opened my eyes and was like, 'You need to move on.' I need it to be done.''
