Kris 'brings Kim and Rob together'

Kris Kenner reportedly forced Rob and Kim Kardashian to make up.

The siblings have had a rocky relationship for some time, with Rob noticeably absent from Kim's lavish Italian wedding to Kanye West in May 2014.

The situation has seemingly thawed though, and 34-year-old Kim even recently told her Twitter followers she'd been working out with Rob, who has shed quite a bit of weight recently. The good will is apparently all down to the family matriarch.

"Kris read them both the riot act and pointed out that this is the worst possible time for the family to be feuding,” a source told Radar.

“Since Caitlyn‘s [Jenner] transformation she’s been quick to point out to everyone in the clan that they need a show of unity, or risk being seen as too fractured and dysfunctional for many of their sponsors and investors."

Caitlyn, formerly known as Bruce, was Kim and Rob's stepfather and despite no longer being married to Kris, the family all remain close.

The Kardashians and Jenners all seem in a good place though, and Rob, 28, has been working hard to slim down. His struggles, like most of the problem's the family face, will reportedly feature on upcoming episodes of their reality TV show.

"[It] will be a focal point on Keeping Up with the Kardashians and Kim’s savvy enough to realise she needs to get behind Rob if she wants to come across well in future episodes," the insider said.
