Only another b*tch as bad as Kris Jenner could drive the Kardashian matriarch to drink! Yep, Caitlyn!

Caitlyn Jenner has been making the rounds doing interviews to promote her upcoming book The Secrets of My Life which is basically one big b*tch slap to all of Cait's KarJenner family, and Kris is pissed! So what better to do than to drown her sorrows in a beautiful, cool glass of Malibu chardonnay!

Daughter Khloe took Kris for a wine tasting in the 'Bu Tuesday -- both ladies were dressed to the nines, of course. Khloe looked sexy as hell in a white body-con dress, covered in a camel coat. She accessorized with a Gucci bag, Louboutin heels and the hottest hair ever. Kris wore wide-legged white pants with a black top and long white coat. These ladies looked like they stepped out of a dreamy garden party ... and X17 was invited! Check out the exclusive pix and video of these two as they shot scenes for KUWTK.
