Rebecca is looking amazing

Rebecca Adlington has wowed by unveiling a new slimmer figure.

The swimmer’s fiancé Harry Needs proudly shared a Twitter snap of the 25-year-old looking happy and toned in a figure-hugging blue midi dress earlier this month.

In the photo, Rebecca shows off her slender arms by placing one hand on her hip and elongates her defined calves in a pair of black peeptoe heels.

‘Wowers @beckadlington looking absolutely smoking tonight, can’t wait to put another ring onit 🙊 #weddingcountdown,’ Harry, 22, captioned the picture.

It’s thought that Rebecca – who’s won two gold and two bronze Olympic medals – has lost at least 2st since retiring from the sport in February last year.

While swimming, she reportedly had to consume around 3,500 calories per day but is now working as a poolside commentator at the Commonwealth Games in Glasgow.

Fans think Rebecca is looking incredible.

‘Rebecca you look AMAZING! Well done and well done too on your Commonwealth commentary, fab fab fab!’ Tweeted one.
