Prince William is set to marry Kate Middleton after the Royal couple got engaged while on holiday in Kenya.
The Queen is "absolutely delighted", Prince Charles is "thrilled" and the Prime Minister has said "it's a great day for Britain".
The Prince proposed with the same diamond and sapphire ring his father gave his mum when they got engaged.
And get this... Even though he's in line to be King, William still went to Kate's dad to get permission before asking her to marry him.
