Kim Kardashian knows how to kick off a birthday.
While the Keeping Up With the Kardashians star shied away from a video post today, Kim couldn't help but to gush over her sister Kylie Jenner, who just turned the big 1-6.
"Happy Birthday to my baby sis @kyliejenner !!!! Can't believe your 16! I love you so much!," Kim wrote on Instagram Saturday, posting a photo of Kylie and Kendall when they were kids, along with a more recent shot.
And that wasn't all.
"More bday love for my muse & baby sis @kyliejenner," Kim went on, posting a collage of herself with Kylie through the years.
While Kylie seemed to be enjoying her birthday, after what appeared to be a celebration that kicked off at midnight.
"16 haaaay," Kylie tweeted, followed by "Love everyone who called and saw me at midnight! Got the best friends & family!"
