Bruce Jenner reportedly feels like most of his family is putting on an act for the press when it comes to his gender transition.

The 65-year-old former Olympian, who is allegedly in the process of becoming a woman, is keeping his distance from the Kardashians because they are not as supportive as they appear, Us Weekly reported.

"Besides Khloe, the Kardashians were not on board with his [male-to-female] transition," a source told Us of Bruce's ex-wife Kris Jenner and stepchildren Khloe Kardashian, 30, Kourtney Kardashian, 35, Kim Kardashian, 34, and Rob Kardashian, 28.

"His boys, [Brody Jenner] and [Brandon Jenner] stuck by him, but Bruce feels like Kris and her girls only support him publicly to make themselves look good."

Although it's not clear how Kendall Jenner, 19, and Kylie Jenner, 17, feel exactly about Bruce's transformation, Bruce's ex-wife Linda Thompson and son Brandon reportedly shared their thoughts with Diane Sawyer during Bruce's highly-anticipated interview, which is scheduled to air on the April 24 20/20 episode at 9PM ET/PT.

Another source explained Bruce is trying to take full advantage of his newfound freedom from Kris, especially when it comes to managing his own finances, but he may be going a little too far.

"He's constantly buying his girls gifts all of a sudden and everyone's worried that he's acting out or trying to buy affection," the second source told Us. "They are all trying to talk him into spending less, but he's doing things his way now."

An additional promo was just released for Bruce Jenner: The Interview. No information was disclosed except for Bruce telling Sawyer: "My whole life has been getting me ready for this."
