Athletics star Jessica Ennis has received a CBE from the Queen - but was so nervous she forgot what she said.

The 27-year-old, who took heptathlon gold in last year's London Games, arrived at Buckingham Palace with fiance Andy Hill, whom she will marry this year. Ennis, wearing a figure-hugging Antonio Berardi dress, said: "I'm feeling very excited, though it was nerve-wracking before. It's incredible to receive this."

Asked what the Queen said, Ennis replied: "You know when you're so nervous and you forget? She just said the summer was amazing, 'How's training going?', so it was very, very nice. It's all going well (training). I've had a bit of a cold so had a few days off. I've been training hard the past few weeks, it's going well."

Ennis was at the centre of a feel-good summer last year as Team GB made the nation proud with its Olympics medal haul. She added: "It still doesn't feel real, to be honest. It was just an amazing year for British athletics and British sport, and to be part of that in such a big way was incredible."

2013 will be another big year as the athlete is set to marry Mr Hill in the spring. "It's an exciting year again, with lots of planning and things to look forward to," she said.

Ennis was joined by a host of other sports stars in a who's who of Olympic champions. Sprint cyclist Jason Kenny, 24, was awarded an OBE, with MBEs going to long jumper Greg Rutherford, 26, flyweight boxer Nicola Adams, 30, and cycling team pursuit gold winner Joanna Rowsell, 24.

Performance director of British Cycling Sir David Brailsford was given a knighthood for services to cycling and the London 2012 Olympic and Paralympic Games. Sir David led Britain to eight cycling gold medals for a second successive Olympics and Team Sky to a historic one-two in the Tour de France in 2012.

Robert Croft, 42, was awarded an MBE for services to cricket following his 23-year career with England and Glamorgan. Bletchley Park codebreaker Raymond "Jerry" Roberts received an MBE for services to the Second World War decryption centre and to codebreaking.

Cherie Blair received a CBE for services to women's issues and charity. The award came after she used the prominence she gained as wife of former prime minister Tony Blair to raise both funds and awareness for a wide range of charities at home and overseas.

She is patron of Breast Cancer Care, Refuge, Scope and the Community Foundation for Merseyside, honorary vice-president - and formerly president - of Barnado's, and president of the Loomba Foundation, which campaigns to alleviate the plight of widows around the world.
