Khloé and Kim Kardashian Flaunt Their Favorite New App—Even Though It's Kind of Vintage

The Kardashians love to have fun, and they showed off just how much fun with their fave new app.

No, that's not the most epic photobomb since that famous stingray.

It's a pic that Khloé Kardashian Odom posted to her blog with the caption, "Party of Five."

The bedazzled shirt, cane and enthusiastic grandma are all courtesy of an app called InstaGranny.

But it's not just Khloé who's having fun inserting new members into the Kardashian gang, even Kim Kardashian Instagrammed an InstaGranny into her life.

"The new Golden Girls," she posted. Well, you all are in Miami, and now you have some old lady street cred...We would totally watch that show, just saying!
