10 times Duchess Kate and Pippa Middleton were #sistergoals

One of our favorite sister acts, Kate Middleton and Pippa Middleton are an inseparable team, from their childhood adventures to their roles as brides. In a 2014 interview with NBC, Pippa emphasized their 'very normal' sisterly relationship, saying: “We’re very close and we support each other and get each other’s opinions.” Take a look at their sweet bond over the years! Kate and Pippa, who both love tennis, attended the 2012 Wimbledon Championships together. The duo have spent many matches together and with their significant others in the stands.

Kate and Pippa were twinning as bridesmaids at their uncle's 1991 wedding. When they were younger, the sisters helped out in the family business and reveled in country walks and cozy Christmas celebrations at which their father Michael would amuse them by wearing costumes, one year even making an entrance as a sumo wrestler.

The Middleton girls’ charm has much to do with the example of their supremely calm and collected, elegant mother Carole, who never seems overawed by her daughter’s royal in-laws. Together she, Kate and Pippa make a formidable trio who stay right up to date on each other’s lives, and love to exchange clothes and make-up tips. Photo: Getty Images
