Whilst many of the celebrities on this list have an undeniable similarity, these two could actually be twins. They've been at the same parties or gatherings on numerous occasions, leaving guests very unsure of who they're talking to.

We hope that doesn't mean she misbehaves, and lets her doppelganger take the blame.
