There's no denying that the Duchess of Cambridge has a lovely relationship with her royal in-laws, particularly Prince William's cousin, Zara Tindall. Since Kate began dating the Prince during their university years, she and Zara appear to have developed a close bond and have been pictured chatting and laughing on several occasions.
The pair will have no doubt swapped wedding planning tips as the Cambridges and the Tindalls both tied the knot in 2011, and were guests at one another's nuptials. Kate and Zara have since become mothers with children of a similar age and the families have been spotted on playdates together.
William and Kate are parents to Prince George, eight, Princess Charlotte, six, and three-year-old Prince Louis, while Zara and Mike have Mia, who turns eigtht on 17 January 2022, three-year-old Lena and son Lucas, who was born in March 2021.
