The news of her pregnancy has come as a big shock but I am absolutely delighted for Jess and Andy. Who knows we may have another Olympic champion! It will be a massive change for her but she has told me she is desperate to defend her Olympic title at Rio, so hopefully that will be the case.
Ennis-Hill, 27 and from Sheffield, who married long-time partner Andy Hill in Derbyshire last May, said in a statement released by her management:
I have some very unexpected but exciting news to share - Andy and I are expecting a baby.
We are completely overwhelmed, with excitement and a degree of anxiety that I am sure all first-time parents will relate to.
My plans for 2014 have been completely turned upside down, but having had a couple of weeks to think about things from a career point of view I am 100 per cent set on returning to full-time athletics once our baby is born and go for a second gold medal at the Rio Olympics in 2016 - that challenge really excites me.
But in the short term I will make our baby a priority and enjoy the whole experience as much as possible.
I am sorry I won't be in Glasgow for the Commonwealth Games, but know it will be an amazing occasion. I will be at home awaiting the arrival of a little Ennis-Hill.
