Maybe they’re born with it! They say that lightning never strikes the same place twice, but the opposite seems to be true for celebrity siblings. Famous brothers and sisters, such as Kate and Oliver Hudson, Cara and Poppy Delevingne and the Baldwin brothers appear to have star power running in their genes.
Born to the same parents, these relatives not only followed similar life paths, pursuing careers in acting, music, sports and reality TV, but made names for themselves apart from their famous family members.
Things can get literally competitive for some — Serena Williams, for instance, has been forced to compete against big sis Venus for a Grand Slam title; others, like Kate and Rooney Mara and Dakota and Elle Fanning, have gone against one another for the same part.
They can also get ugly: Spencer and Stephanie Pratt have butted heads more than a few times, as have Teresa Giudice and Joe Gorga.
Through it all, however, these family members seem to have each other’s backs when it matters most.
