Kylie & Kendall Jenner Indulge on Cake to Celebrate 10 Years on TV!

Can you believe that Kylie Jenner was only nine years old when Keeping Up with the Kardashians first aired, and Kendall was 11?

The sisters have starred on their reality show for 10 years now, and they’re marking the occasion in style!

They were spotted heading into the studio to film the anniversary special on Thursday (April 27) in Los Angeles.

They were joined by Khloe and Kourtney Kardashian, as well as Scott Disick, and their mom Kris.

Also in attendance (via Snapchat) were Kim and stylists Jen Atkin and Simone Harouche.

The famous family took to social media to document some of the festivities, which included 40-ounce bottles of ros� wine, cake, and lots of photo booth fun. Head to our gallery to see all the pics!

The first episode of the E! reality series premiered on October 14, 2007. We can’t wait to see what the anniversary episode has in store later this season!
