Rob Kardashian reveals his favorite sister

OHMYGOSSIP — Rob Kardashian says Kylie Jenner is his favorite sister. The reality 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 affections.

“My favorite sister is my youngest one, Kylie,” he told Us Weekly magazine.

Rob, 25, also let slip a number of surprising details about his life including an embarrassing sleeping revelation and an obsession with germs.

“I sleep with my baby blanket, Kiki, that my Nana made for me … I sanitize all the phones in my house weekly,” he said.

Recent reports claimed Rob visited the offices of a top plastic surgeon that Kim highly recommended and ironed out his face with Botox injections.

“Rob was complaining about his face drooping and that he’s starting to look old,” a source said.

“Kim told him to stop whining and put his money where his mouth is. She turned him on to her trusted plastic surgeon and convinced him to go for a Botox treatment. Rob was all for it and made an appointment right away. Rob may be young, but he’s just as vain as his famous family.

“And it’s no secret he’s been pampered from birth. Rob loves to get manicures, pedicures, facials and skin treatments – he even loves bubble baths. His main concerns about getting Botox were having a stiff face that didn’t move and what his buddies would say.

“The doctor he went to was a pro. Rob’s face felt a little weird, but he walked out of the Beverly Hills office feeling like a new man and more confident than ever. It was just what the doctor — and big sis Kim — ordered.”
