Are Kate and Wills feeling broody? The pair spent Father's Day cooing over his cousin Peter Phillips' baby at the Beaufort Polo Club in Gloucestershire.
Duchess Kate seemed to be having a whale of a time with her puppy Lupo and Autumn and Peter Phillips' daughter Savannah.
Prince William, meanwhile, spent time fussing the couple's latest addition to the family, baby Isla Elizabeth, in between showing off his polo-playing skills.
And, of course, Kate dressed the part in a pair of £300 Le Chameau wellies, which she'd also worn earlier in the day to spend time with the Expanding Horizons primary school camp in Kent.
But although she splashed out on the expensive leather-lined footwear, her jeans were a thrifty £29.99 from Zara.
Kate also showed off her love for Zara on Saturday night during a trip to the theatre to see The Lion, the Witch, and the Wardrobe when she worked a pretty blue bejewelled dress.
