While having a successful career in show business requires hard work and talent, genetics can also play a huge part. While most local celebs are easy on the eyes, it's time to turn our attention to their siblings who have chosen to stay out of the limelight.

For starters, did you know that One Direction member Harry Styles has a beautiful sister named Gemma? Or that Bettina Carlos has two really attractive brothers? In the world of showbiz, you rarely see the appearance of the stars’ family members unless they're entertainers themselves. But when you do, you’ll realize that good looks definitely run in the family – and here’s proof:
