The siblings showed their own version of public displays of affection earlier this week, when they took to social media to share with the world just how very close they are. It started when Rob declared Khloé his "woman crush Wednesday" by tweeting a very bootylicious photo of his sister leaving the gym in some figure-flattering, black Nike running pants.
Khloé quickly acknowledged Rob's tweet by posting a screen grab of it with the caption, "Totally normal brother/sister relationship. Incest is best!!!! #HeyBooHey."
We're positive this interaction was all in good fun. It's even pretty darn cute that Rob is basically saying that he thinks his big sister is beautiful. It's just that any time you slip the word "incest" in there, things are gonna get creepy in a hurry.
Khloé and Rob have always seemed pretty tight as far as the Kardashian siblings go. Rob lived with Khloé and her now-estranged husband, Lamar Odom, in their mansion in Calabasas, California, for a while and the two have stuck by each other's sides through hard times. Khloé later admitted that she felt guilty because Odom had been a bad influence on Rob and contributed to his drug use. "Rob has said, 'Being in that house was so dark and made me do dark things,'" Khloé said on an episode of Keeping Up with the Kardashians. "Only Rob and Lamar know what happened in that house and what's going on... I was not there to protect Rob. I was not there to protect myself."
This isn't the first time Rob and Khloé have shown social media love. Back in February 2013, Rob was rebounding from his breakup with Rita Ora and trying to whip his body back in shape. "I have the best brother in the world," Khloé tweeted on Feb. 20 and then followed that up the next day with a retweet of Rob's diet and workout plan with the caption, "I believe in YOU." Sources say that the two are currently workout partners and Khloé is still trying to help her brother stay healthy.
