While we previously had heard that her last public appearance was to be on June 13, Kate Middleton will make one more appearance before she goes on maternity leave. On Saturday, June 15, the Duchess of Cambridge will be attending Britain's annual Trooping of the Colour, a celebration of Queen Elizabeth II’s birthday.

Recently, Kate attended another Queen-related celebration: her coronation anniversary.

Ever the busy bee, Kate will still be christening that Royal Princess (redundant much?) cruise ship on June 13.

It must be nice to have her plans for that weekend solidified, because things seem pretty up in the air for this Saturday! She and William have four weddings to choose from. Oh, the life of a princess!

Will you miss seeing Kate’s bump everywhere? What do you think she’ll wear to the party?
