text: With seven gold medals, two Olympic Games, an OBE and a stint in the I'm A Celebrity! Get Me Out Of Here jungle under her belt, there's not much that phases former Olympic swimming champion Rebecca Adlington. But at eight months pregnant with her first child, the 26-year-old has revealed being an expectant mum has been one of her toughest roles of her life so far. In an interview in the Sunday Mirror the gold medal winning athlete says the extra pounds she gained in the early stages of her pregnancy were hard to deal with, especially as she didn't even look pregnant and was used to being in charge of her body.

She says: 'I put on a stone and could no longer fit in my clothes, but I wasn't ready for maternity stuff. I didn't feel good about myself.' Rebecca married fellow swimmer Harry Needs, 23, in September 2014 and discovered she was pregnant soon after their honeymoon. Having lost 21lbs after appearing in ITV's I'm A Celebrity! Get Me Out Of Here in December 2013 by avoiding carbohydrates, Rebecca, who is expecting a baby girl, says she's now 'craving stodge'. She also revealed she can't wait for her pregnancy to finish and is fed up of becoming breathless walking up a flight of stairs. She said: 'I'm over it. I don't want her to arrive yet because it's not time, but it's dragged a lot. I want to get back in shape and feel like myself again.'

With a family history of miscarriage, Rebecca says she has been especially careful throughout her pregnancy, and has been swimming and going to the gym to keep fit. Her daughter is due on June 4 and she is planning a water birth, which she believes is 'logical' given that the baby is in water now. She said: 'It's better for me to be relaxed. Plus I'm used to being in water. The one thing I've said is, Harry's not coming in the pool with me - it's my space.' And with her best friend's wedding, at which she will be bridesmaid, in August she is determined to get back her pre-baby figure as soon as possible. Rebecca shares the record for Great Britain's most decorated female Olympian after winning two gold medals in Beijing in 2008 and two bronzes at London 2012. After retiring from competitive swimming in February 2013 Rebecca now runs Becky Adlington's Swim Stars, a swimming academy which runs across the UK teaching kids aged three to 11.
