Leave Blac Chyna! See How Khloe Kardashian Is Fighting To Win Rob Back

The mansion must be lonely all by herself! Khloe Kardashian was feeling pretty sentimental this week about her little brother Rob no longer living with her, and posted the cutest throwback of them!

The 31-year-old shared a black-and-white selfie on Instagram, which shows Rob, 28, kissing her cheek. But it was her caption that grabbed everyone’s attention. “It’s simple…..I miss you,” she wrote along with 3 crying face emojis. Aw!

Though Rob currently lives with his girlfriend, Blac Chyna, prior to that, he was living with Khloe for years. He lived with her when he was married to Lamar Odom, and continued to afterwards while he was battling depression and dealing with his weight gain.

And it sounds like KoKo wants him to move back out of Blac Chyna's place and into hers. Last year, she told Complex mag, "Rob lives with me now and I wouldn't have it any other way. I love having him with me."

But clearly things are different these days, and Khloe doesn’t seem to be a big fan of the change.
