Kim Kardashian went all yee-haw for her daughter Chicago‘s 7th bday!

KK hopped on Instagram Sunday to share a series of photos celebrating Chicago’s big day — which was January 15 — at their beautiful home with a cowgirl-themed party.

Check out the video/pics … Chicago looks cute as a button in her white get-up with her name emblazoned across her back in glittering letters. In the video, KK gave a little tip of the hat to Beyoncé by playing the superstar’s tune, “Texas Hold ‘Em.”

As for KK, she got in on the whole cowgirl theme as well … the Skims founder sported a mostly all-black leather outfit, including an unbuttoned shirt, western belt and blue jeans under a pair of chaps.

KK made the day extra special for Chicago, serving up a personalized birthday cake with “Chi” scrawled on top. Of course, Chi was partying it up with her little brother Psalm and Khloe Kardashian‘s two kiddos, son Tatum and daughter True.
