The Kardashian sisters’ lil brother Robert Kardashian is reportedly dating porn star Lisa Ann, who is best known for the adult movie classic “Who’s Nailin’ Paylin?” (SFW video). Rob is 22 and Lisa is 37! But if it’s true love, age is just a number!

Lisa told TMZ, “Rob treats me like his little teacher and we have a fun sexual relationship that is simple and carefree. He brings out the total cougar in me and I just like to teach him things.”

Robert and Lisa met at the gym around the time of Khloe’s wedding. We hope Robert doesn’t rush into things like his sister Khloe or there will be another wedding soon. Rob and Lisa do make a super cute couple…. Ew!
