Rob's famous sisters have been showing support for their baby bro recently as rumors of him going to rehab swirl, and questions regarding his absence from Kim and Kanye West's wedding continue. Most recently, he's been dealing with the backlash to an interview ex-girlfriend Adrienne Bailon gave Latina magazine saying she regretted being with him and the Kardashian family.

Despite any trouble the family might be having, they are right by his side. Khloe Instagrammed a sweet photo of her and Rob on Friday morning (August 8), saying: "I'll never let you carry more than you can hold my sweet brother. Almost home kiddo!"

While Khloe wraps up her “Kourtney & Khloe Take The Hamptons” shoot, Rob hears her loud and clear.

"love you," he wrote.
