And where will you be watching it, along with billions of other viewers around the world?
Well, Debi Lilly, celebrity event planner and owner of A Perfect Event is going to be in London for the wedding.
But this morning she's right here to share all her tips, tricks and trends for your very own wedding party - a Royal Wedding Breakfast.
Now this is one BIG reason to throw a party - I remember waking up with my grandmother for Lady Diana's wedding and watching it together in the dark of night at 4 am in Ohio...
And now we get to do it all over again - but with party details to boot. So phone a few girlfriends, and invite them over in their pjs for a Royal Wedding Viewing Party.
Start by setting a bar/buffet table in Kate and Lady Diana's favorite color - Wedgewood Blue - so named for an English China company dating back to the 1700s. For a centerpiece fit for a queen, or two, layer in candlesticks of all shapes and sizes, for flickering candlelight and drama on your table. You can even use glass bottles, wine bottles, whatever you have in your home. Tuck in British Flag pennants, crown pennants and more by printing these onto cardstock at home on your computer, and taping onto a skewar. Finally, layer in votive candles, scatter rose petals, and you have an instant, romantic themed tablescape.
Next, design personalized cocktails. Guests love to taste something new, and learn something fun about Kate and Wills.
Her favorite cocktail at London hotspot Mahiki is their signature Pina Colada. These are colorful for spring and taste delicious. You can premake these in pitchers and set the bar with fun fruit mix ins for an interactive bar. At Public, the London club owned by the Prince's good friend, the Champagne Cocktail is his go to drink. Everyone loves to toast the wedding with a little bubbly - and adding fruit as garnish makes it perfect for breakfast.
The English are famous for breakfast - so serving the British classics like Bangers and Mash (sausage and mashed potatoes), Smoked Salmon and Scrambled Eggs, Bubble and Squeek (Hash Browns with the kitchen sink of chopped veg), Scones and Muffins with Jam and Marmalade, mini English Trifles (beautiful layered fruit, sponge cake, spiked creams) and Figgy Puddings.
For dessert top cupcakes with personalized crown, british flag, and monogrammed labels, flags and pennants. This is an instant custom design that you can make at home on your computer, and gather the kids round the table to assemble. These beautiful pearlized, royal wedding cupcakes are from Swirlz in Lincoln Park.
