Khloé Kardashian has sent a short but poignant message to her brother Rob Kardashian. "It's simple… I miss you," the 31-year-old wrote alongside a throwback photo of the siblings together, adding three crying emojis next to the black and white snapshot of Rob giving her a kiss on the cheek.

Khloe's messages comes as Rob's new romance with Blac Chyna continues to blossom. Since the pair started dating, 28-year-old Rob seems to have emerged from his self-imposed exile, and has been looking noticeably slimmer in recent weeks.

It's simple..... I miss you 😫😫😫

On Thursday, Rob and Blac were photographed leaving a gym together after a workout, and later that same day, the smitten TV star beamed a huge smile as he posed in a Snapchat video with his girlfriend, with fans remarking how much happier he now looks.

But, while Rob's romance with Blac is going from strength-to-strength, his relationship with his sisters seems to have hit a rocky patch.

Khloé in particular is said to be struggling with her brother’s new situation – she and Rob are very close, and lived together for much of the time he was struggling with his weight and with depression.

"Khloé feels majorly betrayed by Rob after she always stuck up for him," a source told Us Weekly. "She feels like this is a major blow to the family. Nobody in the family likes it."

Indeed, in late January a family friend told E! News that Khloé , Kim and Kourtney are all "livid about the relationship and not supportive of it at all."

A second source added: "All the sisters are united and think Rob is being disloyal. They want him to be happy and they're so over the whole thing."
