Kylie also thanked her sister for keeping her positive.
The Kardashian-Jenner clan has always been close, but on Monday, Kylie Jenner picked a favorite. The social media-savvy star took to Instagram to wish her eldest sister, Kourtney Kardashian, a happy 37th birthday with a funny video.
“Lol I love you Kourtney,” she captioned a Face Swap clip. “You already know you are my favorite sister these days.. Thank you for teaching me to see the glass half full through everything. Happy birthday ps. Mom in the background.”
The sisters spent the weekend apart with Kourtney celebrating her birthday in Iceland and Kylie partying at the Coachella Music Festival with her older sibling’s ex Scott Disick, Kendall Jenner and her boyfriend Tyga.
It’s been a tough year for Kourtney, who split from Scott in early July after the businessman was spotted canoodling with his ex, Chloe Bartoli, in the south of France.

Since then, the former pair have worked hard to co-parent their three children, even attending family events together.
Scott also praised his ex on her birthday, posting a throwback photo of them making out with the caption: “Happy birthday @kourtneykardash everyone who knows you loves you so much!”
