It wouldn't be a Kardashian-Jenner birthday without some social media dedications.

Kourtney Kardashian turned 38 on Tuesday, and in celebration, her family sent her some well wishes on Instagram.

Khloe was the first to post a video for her older sister, which included some TMI moments of the mother of three. In one scene from the montage, Kourtney is on the toilet and Khloe is asking her if she's a celebrity. "I'm a celebrity, get me out of here!" Kourtney declares.

"Happy birthday to the Milly to my Vanilli @kourtneykardash," Khloe, 32, captioned the video.

Kourtney's mother, Kris Jenner, gave a more sentimental tribute to her oldest daughter, with a photo collage of flashback pics. "Happy birthday beautiful @kourtneykardash!!! From the day you were born, you have blessed me with so much joy! You bring happiness love and light and are such an inspiration to me, and everyone around you," the 61-year-old momager wrote. "You are such an incredible mother, sister, friend, and daughter and I love you more than words can ever say. You are beautiful inside and out, my sweet girl. Have an amazing day, mommy. xoxo #love #family #grateful #happybirthdaykourtney"

Kourtney's sisters, Kim Kardashian West and Kendall Jenner, took to their websites to wish her a happy birthday. "I hope you have the best birthday, Kourtney!!!" Kendall, 21, wrote. "You do so much for everyone else, so I hope you take the day to treat yourself. I love you!"

Kim, 36, also gushed over her big sis, and shared a video tribute. "Happy Birthday to the best older sister. I’m so blessed to have you in my life," she posted. "I love how close we were growing up -- and still are today. I don’t know what I would do without you! Love you!"

When they're not posting birthday wishes, the Kardashian sisters often use their social media accounts to share pics and videos of their group workouts. In January, ET talked with Khloe about exercising with her siblings, and she admitted that Kourtney has come a long way. "I always thought that Kourtney was like a little bit of a p-*-*-s-y in the gym so I would never work out with her, because I'm a beast in the gym," she quipped. "But now we've worked out together and I'm like, 'Kourtney is badass.'"
