Mother Kris Jenner recently admitted that her son Robert is "struggling" and now Khloe Kardashian has suggested that all is not well with her brother.
Taking to instagram, Khloe, 29, shared a sweet photo of herself and Rob as children.
She captioned it: "I miss my best friend @robkardashian"
Rob reportedly deleted ever single one of his family members from his Twitter account, barring sister Kylie Jenner and momager Kris.
He even missed sister Kim's wedding to Kanye West.
Sources told TMZ that Kim’s little brother hurriedly left Paris on Friday after reportedly refusing to pose in wedding pictures with his family because of his weight insecurities.
His family tried to get him to stay and was heartbroken when he decided to leave. Rob was spotted in the Paris airport reportedly “in tears.”
Speaking about Rob, mother Kris recently revealed that her son was going through a difficult time.
She said: "He is struggling with some stuff but my job is to be there for him and love him as hard as I can.
"Everyone goes through stuff and we get through each other's adversity one year at a time."
Rob has withdrawn largely from public life of late as well as restricting his appearances in the show that made his family famous.
Kris also told The Today Show: "Rob is working on himself. He's going to be okay. A lot of prayer and, you know, he's such a great human being … he's my heart."
