Brody Jenner and Kim Kardashian

When it comes to Brody Jenner's relationship with stepsister Kim Kardashian
, there's no bad blood.
After The Hills
the Keeping Up with the Kardashians
to Kanye West
, rumors swirled that the siblings may be squabbling – but Jenner says that simply isn't true.
"Not going to Kim's wedding was not me trying to diss her and Kanye," Jenner told PEOPLE at Monday night's 9th Annual All-Star Celebrity Kick-Off Party, where he later spun tracks as DJ. "I simply had a very last-minute thing. They didn't want to let people know about their wedding early in advance, and I had already booked gigs in Chicago and some other places, so I was already working."
And as far as the rumors of Kardashian not inviting
Jenner's girlfriend, Kaitlyn, to the festivities? Totally false.
"Of course Kim would let me bring my girlfriend if I wanted to," Jenner said. "I'm her brother – it's her wedding. I am allowed to bring someone if I want to."
While Jenner may have missed out on Kim's big day, he did attend the wedding
of her ex-boyfriend Reggie Bush over the weekend.
"I've been friends with Reggie for a very long time," Jenner explained. "I really love him and he's one of my favorite people on this entire planet. I got to have a really close relationship with him through him and Kim being together."
Despite his absence at Kim's European affair, it's clear that Jenner cares a lot about his stepsister.
"The only opinion that matters in this situation is Kim's, and me and her are good," he says. "She is incredible."
