They may be exes, but Scott Disick still has lots of love for Kourtney Kardashian! The father of three took to Instagram today to wish the Keeping Up With the Kardashians star a happy 37th birthday with a steamy PDA pic. Scott wrote "Happy birthday @kourtneykardash everyone who knows you loves you so much!" The accompanying snapshot shows Kourtney and Scott kissing and making out in the ocean during a past vacation when they were still a couple. Too cute!
