Meet Karla, she's the secret Kardashian sister who's been kept under wraps because she's just too darn sexy. 

the 57-year-old, who's not adverse to dressing up as larger than life ladies (her previous Halloween costumes include homages to Sofia Vergara and Nicki Minaj), introduces herself as "the lesser known Kardashian sister, my name is Karla Kardashian with a K, we're known for our double K's these are double Ks too by the way."

She kontinues: "Since I'm the younger sister I get all the hand me downs so these are Kim’s Shape Ups I'm wearing, this is Khloe's old blouse, and the booty is all mine! I'm a big part of the family, but for some reason I'm always cut out of the show. I understand because they only have 12 reality shows that are on TV 80 hours a week but they didn’t have room for me."

It's OK, Karla, Rob knows how you feel.
