KRIS JENNER is terrified that her youngest daughter, Kylie, is going to get sucked into the controversial Church of Scientology if  she continues to date “Karate Kid” star Jaden Smith – the son of Will and Jada Pinkett Smith.

The budding romance between Kylie, 15, and Jaden, 14 – who were spotted on a series of dates in London in early March – originally earned “momager” Kris’ stamp of approval.

“They were going to be the new Kardashian ‘celebrity couple,’” said an insider. “Kris’ mind was go­ing a mile a minute thinking about all of the business deals she could make in the teen market. But after pals alerted her to the Smith fami­ly’s attachment to Scientology, she started having second thoughts about the relationship.”

According to the insider, Kris is concerned that Jaden will pique Kylie’s interest in the church, which could eventually “go after her money and try to control her career.”

Will has publicly denied that he’s a Scientologist, but he maintains a close friendship with the organization’s most celebrated member, Tom Cruise, and has donated to groups affiliated with Scientology in the past.

 The “Men in Black” star told a reporter: “You don’t have to be Jewish to be a friend of Steven Spielberg. You don’t have to be a Muslim to be a friend of Muhammad Ali. And you don’t have to be a Scientologist to be a friend of Tom Cruise…I respect all people and all paths.”

Still, Kris has her doubts. But insiders insist she has nothing to worry about. “Jaden’s a teen­ager,” noted another source.

 “He’s way more concerned with sports, girls and dating than he is with Scientology.”
