She’s been documenting her fitness journey after welcoming her daughter last year.

And Charlotte Crosby proudly flaunted the results of her impressive weight loss after slipping into a plunging blue bikini for a new Instagram post on Sunday.

Showing off her toned figure, the former Geordie Shore star, 33, slipped into an array of swimwear for the confident clip after revealing that a new fitness app is the secret to her transformation.

Charlotte showed off her weight loss in the plunging blue two-piece before changing into a black swimsuit from her new edit with InTheStyle. 

The reality star sparked a flurry of compliments from her followers who lauded her transformation.

‘You look amazing mama; It’s wonderful to see you just happier again,always keep smiling Charlotte, we all adore you!’

‘You look amazing in your swimwear. Reckon you’d look good in a binbag tbh;’

‘One piece is gorgeous on you. Both are fab but you’re killing the one piece.’

Charlotte has previously credited her post-baby weight loss to the BlitznBurn Fitness app, which offers a series of post-partum exercises that last between 10 and 15 minutes per day.

Detailing her goals for 2024, she previously wrote on Instagram: ‘Improve fitness, lose weight, be consistent.’ 

Charlotte and fiancé Jake pulled out all the stops to celebrate their engagement with a lavish party last week.

The couple got engaged last November – thirteen months after welcoming their daughter Alba Jean.

And now they have finally got round to celebrating the proposal with a spectacular bash with their friends and family. 

The couple rented the luxurious Grantley Hall in Ripon, north Yorkshire, luxury hotel and spa, which also boasted a Michelin restaurant.

Charlotte announced her engagement to Jake last November, taking to Instagram to share a snap of the moment he got down on one knee.

Jake popped the question on a rooftop in Dubai, while surrounded by rose petals, candles and a heart shaped backdrop.

The snap showed Charlotte holding her hands to her mouth in shock, while in the caption she declared herself the ‘happiest woman in the world’.

The TV personality, who had been dating Jake for two years, penned: ‘Happiest woman in the world’.

‘Yes yes yes and yes @jake_ankers you are my best friend you are my life i CANT BELIEVE IM ENGAGED AHHHHHHHHHHHHHHh. Best night ever’.

While Jake shared his own snap of the proposal and wrote: ‘Finally plucked up the courage and did it… I love you with all my heart’.
