Looks like their bond runs deep!

Yesterday, Brody Jenner and girlfriend Kaitlynn Carter cleaned up quite nicely for the nuptials between Reggie Bush and Lilit Avagyan in San Diego and they all looked happier than ever!

"It's go time @kaitlynn_carter yewww @reggiebush," the 30-year-old reality star posted on Instagram along with an all smiles black and white photo of the four.

His attendance comes as a surprise seeing as how he was rumored to have snubbed Kim Kardashian and Kanye West's wedding in May due to not getting a plus-one for his girlfriend; he opted for a DJ gig in Chicago over the star-studded event.

Wonder if the Kardashian clan will be questioning this?
