Whether it's from the pressure to "look good", publicity, health, or simply determination to look and feel better - its not uncommon to see celebs dramatically changing their looks in a matter of months. Some may have had help from personal trainers, dieticians and even surgery, but these celebrity transformations are certainly impressive! Here's our top 13...

1. Sam Smith

Sam Smith may only be 23, but he already has 5 UK number ones, a Number 1 album and numerous awards including an Oscar this year. With all this success, he’s been catapulted into the limelight to become a well known name. But his looks were almost unrecognisable in 2015, after losing 3 stone quite rapidly. Sam reportedly cut out gluten, dairy and refined sugar plus included weight training and yoga into his regime. He’s also cut his hair and grown a beard which changes his look. He may not have had money on his mind, but he certainly put his mind to this transformation.

 

2. Charlotte Crosby

Charlotte Crosby rose to fame in 2011 after appearing in reality show Geordie Shore. She stepped out of the public eye for a few months in 2014 but reappeared looking a lot slimmer and dramatically toned up. As a result she released her first workout DVD 3 Minute Belly Blitz. The DVD was a huge success and so she released 3 Minute Bum Blitz released last year. She’s no stranger to plastic surgery either, having recently revealed she’s had a nose job, and quite noticeably lip fillers.

 

3. Jennifer Hudson

American singer, actress and spokesperson, Jennifer Hudson (34) has dropped 5 dress sizes since first appearing on American Idol back in 2004. She says her weight loss is down to a balanced diet and lots of exercise with the help of her personal trainer. Her new shorter hair shows off her beautiful looks, and adds to her transformation. Hudson says she’s happy with how she looks and feels now, and doesn’t plan to lose any more weight. Never mind American idol, she’s our beauty idol!

 

4. Boy George

Without his trademark hat and eye makeup, the lead singer of pop band Culture Club would look almost unrecognisable since shedding 8 stone. After working out and sticking to a controlled diet with the help of a nutritionist (the same as Sam Smiths!), he now looks vastly healthier and trimmer. It didn’t happen overnight though, taking several years to shed the pounds. He now shows off his newfound cheekbones on The Voice on BBC1.

 

5. Dawn French

Vicar of Dibley and French and Saunders star Dawn French has always been one of our most loved comedians. However she looks vastly different to her Vicar of Dibley days – having lost over 7 stone recently due to health complications. She lost the weight sensibly and steadily through low calorie dieting and lots of walking. Looks like Dawn wasn’t ready to overhaul her look completely though, keeping her trademark dark bob and fringe!

 

6. Ricky Wilson

After landing the job as a coach on The Voice, fans were shocked to see the transformation of Kaiser Chiefs singer Ricky Wilson in 2013. From his rather unkempt style in the days of the band, he’s now seriously polished up his image. After cutting back on booze and fast food which he admits he binged on whilst on tour with the band, he’s slimmed down dramatically. Ricky has also had his teeth done, grown a beard, updated his haircut, and even his lashes are darker now! Forget Ruby, it’s hello Ricky!

 

7. Kylie Jenner

Kylie Jenner looks like a completely different person from when she was pictured just three years earlier in 2012. Kylie finally admitted to having lip fillers, but insists she’d had no other surgery.

 

8. Adele

Adele has become a global superstar and since coming back from a 3-year music break last year, and is looking as stunning as ever. She’s quit smoking, changed her diet and apparently has cut down massively on her sugary tea intake. Not only are these things helping with her voice but she also looks amazing, healthy and happy.

 

9. Claire Richards

She’s best known for being a singer in the 90s pop group Steps, but Claire Richard’s fluctuating weight has also been a talking point. After Steps ended, she gained more than 4 stone, but managed to slim down to a size 10 for her wedding day. Her journey was broadcast on a programme called Claire Richards: My Big Fat Wedding which followed the blonde beauty as she fought to shed the pounds before her wedding, drawing in thousands of viewers. She also cashed in on her weight loss by releasing a fitness DVD in 2008.

 

10. Andy Fordham

Former world British darts champion Andy “The Viking” Fordham, has faced a huge battle with his health over the years having at one point weighed over 30 stone. This was mainly due to his drinking habits, reportedly necking up to 25 lagers before a match.  It meant he ended up unable to complete matches, and more worryingly, his liver was shutting down.  After quitting drinking and changing his diet, he managed to lose an astonishing 11 stone by 2008 and looked like a different person. He has however put much of the weight back on, but hopes to repeat his earlier success again.

 

11. Renee Zelwegger

The critically acclaimed American actress and producer Renee Zelwegger, caused a media storm when she appeared at the 21st-annual Elle magazine Women in Hollywood Awards in October 2014. Many found her virtually unrecognisable, with her famous distinguished look seemingly disappeared. This caused huge speculation as to whether she had undergone surgery. Zellweger responded to the comments, “Perhaps I look different. Who doesn’t as they get older?! Ha. But I am different. I’m happy.”

 

12. Josie Gibson

The Big Brother winner made a huge transformation when she lost an incredible 6 stone, slimming down from a size 20 to a size 8 in just a year. After pictures were published of Josie in Ibiza, she was unhappy with how she looked and decided to make a change. In July 2012, Gibson did a photoshoot for Closer magazine to show off her dramatic weight loss. She has since released two fitness DVDs and a book, as well as qualifying as a personal trainer and nutritional advisor.

 

13. James Corden

He may not look like he’s lost such a dramatic amount of weight compared to some of the other celebs, but James Corden has come along way from his Gavin and Stacey days. Having moved to LA, he has now lost 6stone through strict new eating habits and employing a personal trainer. He took over to host the The Late Late Show, and felt he needed to look the part for his American audience. He looks much healthier and sharper – and is probably a lot fitter to look after his two young children.
