It's no secret Brody Jenner isn't a fan of his Kardashian step-sisters, but he threw a little extra shade toward Kim Kardashian this weekend.

Jenner attended the lavish wedding of Kardashian's infamous ex-boyfriend, Detroit Lions star Reggie Bush over the weekend. He shared a picture on Instagram with his girlfriend, Kaitlynn Carter, and the new couple, Bush and his now wife Lilit Avagyan Sunday.

He captioned the picture, "Congrats @reggiebush !!! #bushwedding."

Not only did Jenner support Bush in his nuptials, he was noticeably missing from Kim Kardashian's Italian wedding to Kanye West on May 24. But what fans observed more was Avagyan's arguably striking resemblance to Kardashian.

One wrote, "Ha think it's funny how reggie's wife looks a lot like kimmy kardashian!!!! Lol :-\ awkward!!!!"

Another added, "The bride...Looks just like @kimkardashian ...Awkaward"

But one fan decided to stand up for the new Mrs. Bush and Jenner. They wrote, "I love it! Everyone looks happy & Brody can give 0 cares about what people think. Reggie is his boy. He's showing support. And contrary to popular belief, MRS. BUSH does not look like @Kimkardashian. She looks like herself, which is Mrs. Bush. LOL"

An insider told Us Weekly, "Brody and Reggie are really good friends. He invited him moth ago with a guest. In terms of Kim, one has nothing to do with the other."

Bush and Kardashian were a hot item for several years. They ended their relationship once and for all in March 2010.
