Now that Kim Kardashian's finally pregnant for the second time after struggling with fertility problems with husband Kanye West, it seems like things have cooled down for the star and she wants to make peace before welcoming North West's baby brother - and that includes making up with Rob Kardashian in 2015!

A few months back, Rob Kardashian's 2015 was revealed to be tough, as it was rumored he'd be suing his family (particularly his mother Kris and sisters Kim, Khloe and Kourtney) over making his private life public through their popular reality show "Keeping Up with the Kardashians," but now it seems things have cooled down with the 28 year-old.

According to The Daily Mail, Rob Kardashian's 2015 beef also involved sister Kim specifically at some point, having posted a downright insult to her on social media at some point by saying she was a "b***h," but it seems they've now buried the hatchet.

Us Weekly reports that Kim went on to her very popular Twitter page (which boasts over 34 million followers) to announce her fans that she'd been on a very tough hike with Rob Kardashian in 2015, so it would seem like they're finally hanging out again.

"Just went on the hardest hike ever today with @robkardashian," Kim tweeted, as many applauded them ending their longtime feud - and a while later, Rob went on Instagram to post a screen capture of his famous sister's tweet.

According to Hollywood Life, just a few days earlier, Rob Kardashian 2015 had gone to Instagram to post an adorable snap of brother-in-law Kanye with niece North, prompting speculation about the family's relationship getting better.

A few weeks back, Kim also shared some sweet information about her brother, saying that right before Caitlyn Jenner's introduction to the world on Vanity Fair, Km had send Robert Kardashian 2015 the photo, and surprised after finding out who it was, he said she was beautiful.
