The two posed for a sexy Christmas pic, are often seen around town together and were even spotted playfully holding hands back in November.
Shortly after the holding hands incident, In Touch spoke with a source who said that Kourt is "jealous because her man and her sister are spending so much time together" and that it's "driving her nuts."
Now, a similar story has surfaced in Star magazine (via GossipCop) and claims that Kourtney is becoming increasingly embarrassed as Khloe and Scott make "a game out of shocking onlookers with their touchy-feely behavior."
They have been spending a lot of time together lately, that's for sure...
While we obviously don't think anything is going on between the two of them, we could see why Kourtney would start to feel a little left out.
Would you be mad if you were Kourtney?
