Some of the people honoured as Orders of British Empire, including gymnast Louis Smith and choreographer Arlene Phillips, have updated their Twitter profiles with their new titles.
Gymnast Louis Smith has said that getting an MBE is a "massive pat on the back".
He told ITV News' Correspondent Nina Nannar that he plans to spend more time getting kids involved in gymnastics, but would not reveal whether he plans to compete in the 2016 Olympic Games in Rio.
Choreographer Arlene Phillips has received a CBE for her services to dance and her charity work for the Alzheimer's Society.
Speaking after the ceremony at Buckingham Palace, the former Strictly Come Dancing judge revealed she wants to reinvent herself as a comedian as she approaches a landmark birthday.
"I want to be funny this year. I'm about to turn 70 so now I can let myself go," she said.
"I'd like to be in a comedy or do something totally over the top, maybe a sketch show."
Sophie Hosking, from Wimbledon, was also awarded an MBE for services to rowing.
The athlete, who won gold in the Lightweight Women's Double Scull at London 2012, learned to row at school in Kingston and now trains at the London Rowing Club in Putney.
