Ka-Ching! Kris Jenner's Boy Toy Demands She Pay Him More Money

Kris Jenner's fiancé Corey Gamble is on the verge of being promoted to husband — and the former road manager wants a pay raise to match!

"Corey's only getting $10k a month for all his appearances on Keeping Up with the Kardashians and to chaperone Kris everywhere, but he's starting to wise up to how things work and figures a promotion should come with more cash," an insider tells RadarOnline.com.

According to the source, Gamble, 34, wants to double his fee, but he's cleverly decided to wait before he asks 60-year-old Jenner to pay up.

"Kris has to pay everyone who appears on the show, but Corey's realized he's one of the lowest paid of the lot," reveals the insider.

"He's waiting for all the storylines to be confirmed regarding their engagement and hopefully then it will be too late for her to change her mind."

But he may be in for surprise since business-savvy Jenner is used to tough negotiations and being in charge.

Laughs the source, "He's under the very false illusion that marrying Kris will make him the 'man of the house' or at least her equal — but he's in for a big surprise."
