Kim Kardashian's stepbrother, Brody Jenner, might be close to her ex Reggie Bush -- but the reality star has banned her family from mentioning his name in front of her new husband Kanye West.

Kanye West Talks Issues With Kim Kardashian

Radar Online reported the news Wednesday, claiming The New Workout Plan rapper is "jealous" and "insecure" of Kardashian's ex and she's doing whatever she can to prevent West from having to hear Bush's name.

An insider told the site, "Kim went out of her way to avoid reading about Reggie's wedding to Lilit [Avagyan] last weekend. She doesn't like to discuss Reggie, not even with her sisters. And Kim did remind her family to not mention Reggie's name in front of Kanye, because he is very jealous of him."

They added that while Kardashian tries to convince West he shouldn't be jealous, he insists on thinking otherwise.

"Kanye thinks that Reggie is still in love with Kim because he married a woman that looks exactly like her. And honestly, that isn't lost on Kim either."

The source also spoke on Jenner's seemingly awkward attendance at Bush's wedding earlier this month. But the source went on to say that Kardashian seemed much happier with Bush than with West.

"Brody has been friends with Reggie for years....Kim was a totally different person [with Bush]. There was so much laughter and joking between them. They were a really cute couple, and very much in love. Kim absolutely lit up when Reggie would enter a room."

Bush and Kardashian dated off-and-on from 2007-2010.
