Kris Jenner has joked she is waiting until the new 'Keeping Up With the Kardashians' series to potentially confirm her daughters' pregnancies - because she ''gets 10 per cent''.

The showbiz matriarch's daughters Khloe Kardashian, 33, and Kylie Jenner, 20, are both said to be expecting, but after a grilling about the subject, the 61-year-old momager remained coy, refusing to be ''tricked'' into confirming the speculation.

During Kris' appearance on 'The Ellen Degeneres Show', the host said: ''You have lots of pregnant children right now. You do. You have a whole bunch of them.''

Kris chuckled and replied: ''Oh, here. I can feel where this is going. She's trying to trick me into confirming pregnancies.''

Ellen then said: ''You're waiting for your show to do it, I know that.''

Kris laughed again and added: ''Well, you know, I get 10 percent.''

The Kardashian-Jenner clan recently penned a deal worth a reported $150 million for more 'Keeping Up With the Kardashians' series, and Kris admitted the family gets paid ''pretty much equally''.

She added: ''It's kind of a group decision. And I'm lucky if I even get paid, by the time the girls get finished with me.

''Everybody gets paid pretty much equally because we all film a lot and we all work hard. And we've created this show and this brand for the last decade so everybody's happy. They're really happy.''

Kris - who has daughters Kourtney Kardashian, 38, Kim Kardashian West, 37, and Kendall Jenner, 22, as well as son Rob Kardashian, 30 - insisted she has no plans for any more kids herself, but joked she might change her mind and have ''a couple more'' if it means extra money.

After Ellen quipped that another child could mean more cash, Kris joked: ''I think she's onto something! I could have a couple more, 10 per cent!''
