This week, Kourtney Kardashian took to her website and app to share not just a photo (or 11), but an entire video in honor of #ThrowbackThursday.
"Since my birthday month is coming to an end, I thought a birthday TBT was appropriate," wrote Kourtney, who turned 37 on April 18.

Meanwhile, this year the star celebrated her birthday in a slightly frostier climate, with a trip to Iceland with Kim and her hubby Kanye West, plus a few other family friends.
A source recently told PEOPLE that the reality star and mother of three is "doing great," and that while "last year was very tough for her" following her split from ex Scott Disick after nine years, she's acting "happier and confident lately."
"It took Kourtney months to get to where she is right now," added the source.
