Rob Kardashian 'in happy relationship with Blac Chyna'

Rob Kardashian is happier than ever now he's in a relationship with Blac Chyna, according to sources.

The reality star has caused a stir by romancing the ex of his half-sister Kylie Jenner's boyfriend Tyga, with whom Blac has three-year-old son King Cairo. On Wednesday (27Jan16) TMZ reported the pair were cohabiting after a fortnight of dating, with Rob's family apparently disapproving.

But it seems things are serious between the couple, as insiders tell the outlet the two are a proper item and Blac is helping Rob to have fun again. The 28-year-old sock designer has struggled with self-confidence issues since being diagnosed with diabetes in 2015, and it's thought Blac is helping motivate him to lose weight.

While many were quick to assume Rob is dating the model to spite his family, who he's had numerous fallings out with, a source insisted to TMZ this isn't the case. "He adores her," the insider said.

Rob is apparently planning to stay at Blac's home indefinitely and has no plans to move back in with his sister Khloe, who is rumored to have kicked him out over the romance after five years of living together.

One person who is thought to have had a change of heart is his sister Kim. This is something of a surprise as her husband Kanye West dated Blac's best friend Amber Rose, who has thrown shade at Kylie and Khloe in the past, as has Blac towards Kylie and Tyga because of their relationship.

Tyga has also briefly commented on the situation while on Khloe's chat show Kocktails with Khloe. When quizzed on his thoughts about the set up, the 26-year-old simply said: “Everybody deserves to be happy."

The rumor mill started spinning on Monday (25Jan16) when Blac uploading a photo onto Instagram. In it she's seen wrapped up in a tattooed arm, resembling Rob's, with the caption "The beginning". This triggered many to assume she was announcing her new relationship, but neither has confirmed anything yet.
