London - Rob Kardashian's favourite sister is Kylie Jenner.
The reality TV star has five female siblings - Kim, Kourtney and Khloe Kardashian, and half-sisters Kendall and Kylie Jenner - and although he gets on with all of them, 15-year-old Kylie has a special place in his heart.
Writing a feature 25 Things You Don't Know About Me for Us Weekly magazine, he revealed: “My favourite sister is my youngest one, Kylie.”
The former Dancing With The Stars contestant also let slip a number of surprising details about his life, including an embarrassing sleeping revelation and an obsession with germs.
Rob, 25, said: “I sleep with my baby blanket, Kiki, that my Nana made for me... I sanitise all the phones in my house weekly.”
Perhaps it is Rob's paranoia about germs that inspires him to maintain high standards of personal hygiene.
He explained: “I get a shave every week and I also get regular manicures and pedicures at my house.” - Bang Showbiz
