Kim Kardashian may be billed as the favourite in her family, but it appears that isn't the case when it comes to Rob Kardashian.
Speaking to Us Weekly, the reality TV star revealed that the youngest of the Kardashian/Jenner clan, Kylie, was his favourite.
The TV star turned sock designer, said: "My favorite sister is my youngest one, Kylie."
We wonder how Kimmy will feel about that!

Rob also made the revelation that he watches the BBC, in particular "Top Gear and Ramsay's Kitchen Nightmares" - a result of dating British star Rita Ora perhaps?
Speaking of Rita, the 'How We Do (Party)' hitmaker appeared to be pretty sure about her feelings for Rob when she told Australian radio show Kyle and Jackie O:
"OK here we go, I would marry Robert De Niro, I would sh*g Robert Pattinson and I would definitely, definitely, shoot Rob Kardashian."
In the interview, Rita also spoke about Twitter, saying: "[Twitter] it is awkward, I also feel like it's a personal choice. If you want to make yourself look a certain way, and feel that's the right way, then that's your choice. Personally, I like to keep things like that private."
