LOS ANGELES, Dec. 15 (UPI) -- Khloe Kardashian encouraged brother Rob Kardashian in a new post Monday on Instagram.
The 31-year-old reality star posted a throwback photo of herself with the 28-year-old sock designer and captioned the picture with a motivational message.
"If only you could see yourself through my eyes! I'll forever be obsessed with you! My one and only! #MyAce," she wrote.
Rob Kardashian has withdrawn from the spotlight in recent years, skipping sister Kim Kardashian's wedding in 2014 and his family's Thanksgiving celebration in November. His reclusiveness appears to be tied to his significant weight gain.
"He lives with Khloe," mom Kris Jenner confirmed to Maria Menounos this month. "He's doing alright. You know, he's doing his best. He's not into being on camera as much as the rest of us. But he's working on himself. He's going to be OK."
Jenner previously expressed concern for her son's health on the family's E! series, Keeping Up with the Kardashians. Rob Kardashian gained more than 100 pounds over the course of a year, but appeared to be back on an exercise regime in September.
