Her Majesty had a lovely group in the Duke and Duchess of Cambridge, Prince Harry, Zara and Mike Tindall and Princess Beatrice. Three out of her four children were also present, with Princess Anne, Prince Edward and Prince Andrew putting on their Sunday best.

The look of love

Happy holiday vibes were coursing through Kate Middleton and Prince William who looked so in love as they made their way into the church. The 37-year-old mom looked lovely in a baby blue Alexander McQueen ensemble. The jacket appears to be the one she wore for Easter back in 2014 when she and William toured Australia.
