Paul Hollywood and Guy Fieri *have* to be related. I can only assume that there is some sort of Parent Trap situation going on here because there are too many similarities for them not to be brothers, or at least cousins! They've both become world famous TV chefs, have iconic spikey hair, and sport perfect facial hair.

4. Katie Price and Kim Kardashian West.

Katie Price walked so Kim K could run. High profile marriages, reality TV shows, and expanding broods are all things these two have in common.
