Khloe Kardashian has been tight with her sister Kourtney’s ex Scott Disick for years. Keeping Up With the Kardashians followers have long wondered if there is something …. More … to their connection.

But the speculation has been rampant lately, and Khloe is responding. Scott recently celebrated his 36th birthday with his girlfriend Sofia Richie, his ex Kourtney, plus Kim, Khloe, Kylie and others. 

They all sent out shout-outs on social media to Scott. Khloe’s post was heartfelt: "Happy birthday to my brother @letthelordbewithyou !!! I am so thankful to have such an incredible addition such as you to our family! We have come such a long way, you and I! I am so thankful for the person that you have grown into. I am thankful for every highs and lows because we have been through it all and we are closer than ever. I am proud to say that you are my brother and also one of my best friends! Have the best birthday Lord!! FOREVER the Lord and the Lady."

Fans flooded her Instagram with messages about their relationship, musing "what is happening here? I sense chemistry" and "damn, why ya'll look so good together," plus "refuse to believe they've never shagged."

Khloe responded with heart emojis to a fan who wrote,"just because two people are close don’t mean they have shagged before," then added a kissy emoji next to a comment that she isn’t the type to shag a sister’s ex.
