The 32-year-old star posted a throwback photograph from 2009 of him and the raven-haired beauty - who he has three kids with, Mason, six, Penelope, three, and 16-month-old Reign - sharing a smooch while taking a dip in the sea.

He added the caption: "Happy birthday @kourtneykardash everyone who knows you loves you so much! (sic)"

The 37-year-old stunner - who split from Scott in July last year after a nine-year relationship - celebrated her birthday yesterday (18.04.16) in Iceland with her sister Kim Kardashian West and her sibling's husband Kanye West.

Scott wasn't the only one feeling nostalgic on Kourtney's birthday as her mother Kris Jenner shared a throwback photograph of her daughter when she was just a baby.

She captioned the photo: "Happy Birthday tomorrow beautiful @kourtneykardash!! I know it's crazy but I remember this pic like it was yesterday.. You have brought so much love, joy, and happiness into my life and I'm proud to be your Mom.. You teach all of us everyday what it means to be an amazing daughter, Mom, sister, friend, and a genuinely beautiful human being. Thank you for being such a bright light and an inspiration to me every day.. You are kind and patient and have the biggest heart and I love you more than you will ever know. You will always be my firstborn who captured my heart.... Oh, and I'm really sorry about this outfit I put you in....I love you, mommy #love #blessed #mybaby (sic)"
