The 'Keeping Up With the Kardashians' star is delighted her reclusive son's sock line, Arthur George - which he launched in 2012 - is going from strength to strength and urged fans to check out his new website.

Taking to her Instagram account on Monday (01.02.16) alongside a photo of the sock collection, she wrote: "OBSESSED with @robkardashian 's socks!!! Check out and follow @arthurgeorge87 and the new website shoparthurgeorge.com #coziestsocksever #proudmama (sic)"

Meanwhile, Rob has now officially signed up to social media app Snapchat, joining under the username 'theshaderoominc'.

His new girlfriend Blac Chyna - who he has been dating for just a few weeks - encouraged her fans to follow Rob's account, but warned girls not to share rude content with him.

She posted on her own Snapchat: "Lemme tell you all something, don't be snapping my boo that p***y. I ain't f**king playin (sic)."

And while Kris is proud of her son, some of the Kardashian family are upset about his relationship with the 27-year-old model.

On hearing her younger sibling was dating Blac, sister Khloe Kardashian took to Twitter with some words of wisdom for Rob.

She wrote: "You can do anything, but don't go against the family."
