KOURTNEY KARDASHIAN is finally set to marry longtime beau Scott Disick after “momager” Kris Jenner turned into a demanding Cupid and ordered them to “cash in quick,” say sources.

The reality TV stars have been an on-again/off-again couple since 2006 and have two children together – son Mason, 2, and 1-year-old Penelope. Now Kris has started pushing them to seal the deal in a bid to keep money pouring into the Kardashian coffers.

“Kris has convinced them they could net a whopping $10 million in deals from their wedding,” a family friend told The ENQUIRER.

“They’ve had a roller-coaster relationship and Kourtney has had to live with all sorts of rumors about Scott’s wild partying with other women. So marriage hadn’t been a top priority for them – that was until Kris gave it to them straight.

 “Kris is worried that the family’s popularity may be on the wane and there may not be many megabucks paydays left. She wants to cash out now.”

The reality TV matriarch 57, is orchestrat­ing every detail. She wants Kourtney, 34, to help get the relationship back in the spotlight, “and she’s told Scott to be as romantic as possible with Kourtney whenever they’re in public,” divulged an insider. Scott appears to be paying close attention. Over Memorial Day weekend, he celebrated his 30th birth­day at a Las Vegas club, and was all over Kourtney, even serenading her.

“They want to build up the hype before Kris starts pitching the exclusive engagement pictures and a wedding TV special,” said the friend. “They want to tie the knot in Aspen in November.

“Kris thinks they can make a fortune, and the couple is onboard provided the money’s there.”
