12 Celebrities Who Prove Little Sisters Are the Coolest

Older sibling: Kate Middleton

Of course Pippa Middleton is going to get away with more than her older sister, Kate — she's doesn't have to worry about pissing off the queen. Really, though, Pippa was branded as the "cool, wild sister" from the second she stepped on the scene in a fitted white dress for Kate and William's wedding in 2011. Since then, we've seen her hitting the beach in a bikini, romancing handsome Brits, hanging out in the Hamptons, and sitting courtside with celebrities at Wimbledon. It's pretty great to see Pippa living it up and enjoying a life that's not under a microscope, without the same pressures that her sister faces as the people's princess.
