Rob Kardashian is back in the spotlight, and appears to be embracing every minute of it.

The 29-year-old reality star took to Instagram to share a Snapchat video of his sister, Kim Kardashian, who seemed to jokingly respond to the chatter regarding their famous family's drama.

"Rob, we really need to talk," Kim exclaimed in the Snapchat, as tears created from one of the app's popular filters ran down her face.

"Had to post this snap my sis sent me," he captioned it. "LOL she's got jokes!"

Ever since Rob started dating his now-fiancée, Blac Chyna, in January, rumors have swirled that the entire family is not happy about it. To make matters more complicated, Chyna shares a 3-year-old son, King Cairo, with Kylie Jenner's current boyfriend, Tyga.

He also shared a Snapchat of Kim using the app's MLB opening day filter.

"In honor of Rob's big day," she said, titling her head to show off the filter's Los Angeles Dodgers logo on a fake fitted hat. (And in case you haven't been Keeping Up With the Kardashians, Rob is a huge fan of the L.A.-based pro baseball team.)

While they seem to be joking around, Khloe chose to highlight a very NSFW old fight the two had during an episode of their hit reality TV series.

"MOOD!!! I wish all fights were like this!" she captioned a video posted to her Instagram on Saturday. "What were they even fighting about?"

Caitlyn Jenner, who had yet to go through her transition, also appeared in the throwback footage. Kim's ex-husband, Kris Humphries, was featured in Khloe's video, too, which is kind of hilarious because just earlier this week, she recalled telling Kim he was a "f**king loser" on Snoop Dogg's GGN web series.

Oh, how the times have changed!

Rob also took to Snapchat Friday night, showing off his "big booty Judy" twerking in skin-tight pants. He even threw some stacks of cash Chyna's way!
