Brody Jenner Attends Kim Kardashian's Ex's Wedding: Jenner Photographed At Reggie Bush Nuptials

Brody Jenner may have missed his step-sister's wedding, but he was sure to attend the wedding of her ex.

Over the weekend, Jenner, who was joined by girlfriend Kaitlynn Carter, was spotted at the Reggie Bush's wedding to Lilit Avagyan, leading many to wonder if there is a feud going on between him and Kim Kardashian.

"Brody Jenner may have made a major party foul. The Hills alum, who was noticeably absent from stepsister Kim Kardashian's wedding to Kanye West in May, attended the nuptials of her ex-boyfriend Reggie Bush on Saturday, July 12," Us Weekly reported on Sun., July 13.

In May, as Kardashian married rapper Kanye West, the father of her one-year-old daughter, North, Jenner was nowhere to be seen, and, according to reports, that was because Kardashian failed to invite his girlfriend of nine months, Carter. However, when it came to Bush's wedding at the Grand Del Mar in San Diego, Calif., both parties were invited and spent the day sharing photos of the event on their social media accounts.

Still, an Us Weekly source claims there is no feud going on between Jenner and Kardashian.

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

Bush and Avagyan began dating after Bush's 2010 split from Kardashian. Last May, the couple welcomed their first child together, daughter Briseis.

Of the wedding, Bush told TMZ, via Us Weekly, "I'm tapped out. The wedding is costing me a lot of money."
