Fans began speculating in the comments section about whether it was actually Kourtney in the photo, or the couple's daughter, Penelope. But the debate ended when many noted that the 8-year-old wouldn't be that tall.
Now that Kourtney and Scott are both once again single, rumors of them potentially rekindling their romance have abounded. Scott has frequently left flirty comments on his ex's Instagram posts, and earlier this month he even teased her as she quoted "WAP" lyrics in one of her captions.
After Kourtney captioned one shot, "I don't cook, I don't clean," Scott replied, "That's for sure."
