Just wait for this storyline on “Keeping Up with the Kardashians.”

Brody Jenner, Kim Kardashian’s stepbrother, attended her ex-boyfriend Reggie Bush’s California wedding on Saturday.

Jenner, 30, posted a few pictures of the event to his Instagram account. Dressed in a black suit, Brody posed with girlfriend Kaitlynn Carter in one picture.

In a second snapshot, Jenner and Carter cozied up next to Bush and wife Lilit Avagyan.

Jenner was noticeably absent from Kardashian’s May nuptials to Kanye West in Florence, Italy.

An insider told Us Weekly that Jenner elected to skip the European three-day affair because his girlfriend didn’t receive an invite.

Despite what could be a messy situation at the next Kardashian-Jenner gathering, a source says things are copacetic.

“Brody and Reggie are really good friends. He invited him months ago with a guest. In terms of Kim, one has nothing to do with the other.”

Bush and Kardashian dated from 2007 until March 2010 when they parted ways for good.
