The Duchess Of Cambridge To Host A Celebrity Gala With The Queen

Kate Middleton's busy schedule just never lets up, does it? And for her latest engagement, she'll be hosting a star-studded party alongside The Queen, honouring the dramatic arts.

Duchess Kate and her grandmother-in-law will welcome around 250 guests to the Buckingham Palace bash on 17 February. And according to HELLO!, there's no shortage of A-list names on the guest list.

The very best of British talent including Benedict Cumberbatch, Helen Mirren, Cate Blanchett and Downton Abbey creator Julian Fellowes are said to be attending.

The party is to honour The Royal Academy of Dramatic Arts (RADA), of which The Queen is a patron. And in the spirit of all things the arts, The Palace will host a series of performances in the ballroom for guests to enjoy after their arrival.

Now there's a party we'd love to be a fly on the wall at!

What will Kate wear? We wonder. Check out her style history for some clues.
