Rebecca Adlington begins maternity leave

Not long to go now before Rebecca Adlington gives birth to her first child. The retired Olympic swimmer, who is known as Becky by her close friends, is preparing to welcome her daughter with husband Harry Needs at the beginning of June.

With only three weeks to go before she meets her little one, Becky set off to Gloucestershire to kick off her maternity leave.

The 26-year-old shared a photo on Instagram from her heavenly pregnancy retreat in the countryside – most likely the last trip she will be taking before she joins the mummy club.

"Absolutely beautiful place to have a nice few days away & a pamper!" Becky captioned the snap. "Incredible pregnancy retreat @retreatyourselfpregnancy!! Just what I needed especially now maternity leave has started :-) #pregnancy #health #relax #pamper #retreat #yoga #food."

Becky and Harry previously revealed to HELLO! magazine that their baby is due on 4 June. The couple, who married last August amid the rural setting of Staffordshire, have been making last-minute preparations for their arrival.

The former Olympic swimmer said she is "super excited" to meet her baby

In a video that Becky posted on YouTube earlier this month, the athlete proudly showed off her daughter's nursery room and gave fans a glimpse at some of the clothes she and Harry had bought for the little tot.

No doubt a swimming costume was top of their shopping list. The pregnant star and her husband, who is also a professional swimmer, said that they couldn't wait to "take her in the pool".

As well as having a cot assembled in the room, Becky also said that her hospital bags are packed and "ready to go" for when she goes into labour.

"Now all we need is her," she added. "We need her to come out. We're just so excited now that the house is finally done. We've only got four weeks left of the pregnancy so hopefully it will go nice and smooth and now we just can't wait to meet her. We're super excited."
