Brody Jenner was recently spotted exiting an airport in Sydney Australia with fans flocking to his side while he was filmed by paparazzi, TMZ reports.

"I appreciate you guys," Jenner told fans in a Dimex video clip obtained by TMZ. "I'm not used to this, to be honest. Maybe if I was Kim Kardashian, I'd be used to it."

At first, Jenner appears pleasant in the video until a photographer asks him a question about his sister Kim Kardashian's experience in Australia.

"Let me tell you something, you ask me some stupid f**king questions like that, I'm not gonna answer them," Jenner tells the photographer.

The video clip continues and we see Jenner become noticeably more irate as the photographer continues to film. At one point, Jenner even attempts to grab the camera from the photographer's arms.

Though it is unclear what specifically sparked Jenner's drastic shift in mood following the Kardashian question, TMZ suggests that Jenner might be bitter towards Kardashian or he might've wanted photographers to focus on him and not his sister.

Either way, it is not shocking to see Jenner become so upset about the Kardashians.

Back in August, Jenner failed to show up to Kim Kardashian's wedding with Kanye West and instead, made an appearance at Regge Bush's wedding, TMZ reports

Reggie Bush and Kim Kardashian famously dated during the first few seasons of "Keeping up With the Kardashians."

At the time of Jenner's attendance at Bush's wedding, RadarOnline reported that Kardashian and Jenner were not friends.

"Publicly the two will say there is no feud, but that is all for keeping up the appearance of having a big extended family for the sake of the E! reality show. Brody never sees Kim except when they are filming, and the two aren't even considered friends," a RadarOnline source said at the time.

Kim Kardashian has yet to speak on Jenner's outburst at the Australia airport.
