Olympic medallist-turned-Strictly Come Dancing champion Louis Smith described his MBE as "without a doubt the proudest moment of my life".
The Peterborough gymnast was a member of Britain's surprise bronze medal success in the men's team competition at the London 2012 Olympics.
He also won silver on the pommel horse with one of the hardest routines in the world.
"To receive this honour is out of this world and something I never would have dreamt of as I grew up in the sport of gymnastics," said Smith, 23.
