Brody Jenner isn't letting Kim Kardashian forget about her failure to invite his girlfriend to her wedding.

Brody Jenner Lands New TV Show 'Sex With Brody' On E!

Over the weekend, while attending the wedding of a friend with Kaitlynn Carter, Jenner, Kardashian's step-brother and Keeping Up With The Kardashians co-star, poked fun at their ongoing feud on Instagram.

"Look…@kaitlynn_carter and I finally get to go to a wedding together!!!" Jenner wrote, along with a group photo of himself, Carter, brother Brandon and mother Linda.

Is Brody Jenner Getting Engaged To Kaitlynn Carter?

"Brody Jenner apparently still holds a grudge against Kim Kardashian, who famously didn't allow him a plus-one to her lavish wedding last spring," the Daily Mail Online reported on Monday. "Bruce Jenner's 31-year-old son took aim at his stepsister when he posted a dissing Instagram saying that 'finally' he and girlfriend Kaitlynn Carter got a couple's invite to a friend's nuptials on Saturday."

Although Jenner was clearly taking a stand against Kardashian, and possibly her husband, Kanye West, he eventually had a change of heart, and removed the post from his feed.

During season 10 of Keeping Up With The Kardashians, Jenner opened up about his step-sister's snub.

"Kim and Kanye — very happy for them, but do you think that they were really like, 'We have to have Brody and Kaitlynn there. If they're not there, then this wedding is not gonna happen,'" he asked. "Nobody really gave a f--k if Kaitlynn or I [came]."
