Kim Kardashian is said to be worried that her mom, Kris Jenner's, new beau, Corey Gamble, has secret motives.

An insider told Hollywood Life Sunday that Kardashian is keeping a close eye on Gamble.

"Kim's apprehensive about her mother's relationship with Corey. He seems like a guy on the surface but Kim doesn't think Kris really knows him.

"She doesn't want Kris to become too attached and fall deeply in love with him just because she's lonely," they said. Jenner just finalized her divorce with Bruce Jenner in December of 2014. The two were married for 23 years.

The source continued and said that Kardashian is concerned Gamble is only dating Kris because she is rich and famous.

"Kim already thinks he's an opportunist, mainly because he's become accustomed to all the money Kris spends on him. She really wishes she wouldn't do that but she can't control her mother."

If this is true, the insider is not the first person to claim that Gamble is just using Kris. His ex-girlfriend, Atlanta Exes star Sheree Buchanan recently said that after they split, he was determined to date a wealthy woman.

Buchanan spoke with In Touch Weekly just weeks after it was confirmed that Gamble and Jenner were a couple.

"I know Corey. He's all about power and money and will do whatever it takes to get it. He sees the Kardashians as media's first family."

She also said she had to get a restraining order against him after their breakup because he was allegedly stalking her.
