Showing off her slim legs and petite frame as she displayed her incredible 3st weight loss in pictures that surfaced last week, Adele was barely recognisable as she frolicked in the Caribbean sea while on holiday with pals Harry Styles and James Corden.
Heaping praise on the singer – who has five-year-old son Angelo with ex-husband Simon Konecki, 45 – one fan gushed on social media, "Good for her, she looks amazing!" While another posted, "Wowsers what a transformation. She’s tiny!"
Last week, Hollywood personal trainer Camila Goodis – who also trains Robbie Williams’ wife Ayda Field – spoke about Adele’s shape-up, saying, "I trained Ayda for a long time and it happens that [Adele and Ayda] are good friends, so I helped Adele when she was at Robbie’s house.
"I don’t believe she liked exercise much, but she has changed her lifestyle and I think 90 per cent of that was dieting."
But insiders tell Closer that Adele, 31 – who has shrunk from a size 18 to a size 12 in nine months – has had a helping hand from ex-1D singer Harry, 25, with whom she’s been close since 2015.
A source says, "Harry was Adele’s rock when she split from Simon last April. He checked in on her constantly, stayed over at her LA mansion whenever she needed company, and generally was an amazing friend to her when she most needed it.
"Harry’s always been very health conscious. After Adele vowed to get in shape, he said he wanted to help her, so took her hiking on some of his favourite trails in Malibu, occasionally did HIIT (high intensity interval training) classes with her, and gave her a hand with meal-planning and cooking to help her stay on track.

"She also started swapping surgary tea for Bulletproof coffee – black coffee mixed with butter and coconut oil – which Harry swears by and he claims it helps him feel full so he can intermittent fast, which Adele said she found surprisingly easy.
"Harry has also encouraged her to cut out meat as much as possible and have a few booze-free weeks, which she’s credited with helping her feel better both mentally as well as physically."
It’s not the first time Adele’s A-list pals have supported her. As Closer previously reported, her friend Beyoncé introduced her to dance classes and the ‘Sirtfood’ diet, which focuses on 20 ‘wonder foods’ – including celery, rocket salad, coffee, and red onion – which is claimed to help boost metabolism.
Their recent holiday also renewed rumours of a romance between Harry and Adele. Harry – who’s previously dated ex-Love Island host Caroline Flack, 40, and singer Taylor Swift, 30 – made no secret of his admiration for the star in the past, revealing in 2011 he would "love to date" the Someone Like You singer, who made him "weak at the knees".
After a flattered Adele called Harry – with whom she shares a vocal coach – "cute", he continued the flirtation a year later at the 2012 Brits, saying he’d love to snog the Oscar winner.

"It’s still early days, but she hasn’t ruled out exploring their chemistry and connection. After all the emotional stress of her split from Simon, she’s finally back to her best and all her hard work to get there means she feels ready to explore a relationship with a new man, whether that’s with Harry or someone else.
"Adele is the happiest she’s been in a long time. A lot of that is thanks the new-found confidence she’s gained, and Harry has definitely helped instil that in her."
