He put a ring on it!

Surrounded by nearly 1,900 friends, family members, celebrities and dignitaries, Prince William, 28, and Kate Middleton, 29, said "I Do" in front of nearly 2 billion viewers on Friday.

The couple, now known as the Duke and Duchess of Cambridge, exchanged loving glances as the Archbishop of Canterbury conducted the romantic ceremony.

After William placed the ring on Middleton's finger, the Archbishop declared: "I pronounce that they be man and wife together!"

As per royal tradition, the newlyweds did not kiss at the altar after the proclamation; they will lock lips on the balcony at Buckingham Palace later in the day.
