Kate lets puppy's name slip!

Kate Middleton has accidentally let the name of her little puppy slip.

After keeping it secret for weeks, the Duchess has finally revealed the name - Lupo.

The name means wolf in Italian. Little Lupo already has his own Twitter page - follow him @HRH_Lupo!

Kate let the name slip during a visit to Rose Hill Primary School in Oxford, where she was helping to promote The Art Room - a charity she has become a patron of.

The black doggy is a cocker spaniel.
