omg! celebrate Kate Middleton’s 30th birthday with Royal tea party, you win tea and cake

Kate Middleton turning 30 seemed like a pretty good excuse for omg! to have a good old British tea party.

We even managed to persuade some Royal guests to come along too - Princes William, Charles and Harry all turned up, along with the guest of honour herself, the Duchess of Cambridge. *giggles*

As you can see, they all had a spiffing time eating scones, playing pool and even munching on some pizza.

We thought we'd share the snaps with you - and let you win some tea and cake. All you have to do is tweet us captions for each picture, using the hashtag #katesparty.
