Ever since we found out that Penelope Cruz has a nearly identical except possibly-even-hotter sister, we've been wondering how many other celebrities have a secretly smoking sibling sunning themselves in bikinis in the branches of their family trees. It turns out, quite a few.

It's not surprising that so many actresses have attractive sisters -- after all, they're drawing from the same superior gene pool as their famous family members. We keep thinking that the non-famous siblings' lack of money and international notoriety might just mean we actually have a chance with the overlooked sisters of hot, famous actresses everywhere.

Casting aside the generally well-known (no Solanges or Jamie Lynns here), click through the gallery to discover the hottest hidden celebrity siblings.
