The ‘Keeping Up With The Kardashians’ star proved that she still cares for her brother, who is dealing with undisclosed issues in his personal life, by sharing a photo of the two of them on her Instagram page.
She added: “If only you could see yourself through my eyes! I'll forever be obsessed with you! My one and only! #MyAce”
Khloé and Rob have always had a close relationship, and she previously posted a similarly touching message on his birthday back in March.
She said at the time: “Never will I ever meet another man as great as you! I know this is the year where you will find your happiness again!
“I will be right by your side, holding your hand, every step of the way!!! I adore you my one and only brother!!”
Rob and Khloé in 2012
Rob is rarely seen in public or on social media nowadays, and he's also no longer in the cast of the E! reality series, ‘Keeping Up With The Kardashians’.
He’s also had a number of fairly well-documented public rows with his famous family, including last year, when he failed to attend Kim’s wedding to Kanye West.
Following this, he later had something of a Twitter meltdown, and unfollowed everyone on his account, apart from Khloé.
