Viewers of The One Show were left stunned this week as Dawn French showed off her new slimmer figure whilst appearing as a guest on the show.

She aimed to publicise her new book ‘Me. You. A Diary’ described as a ‘unique shared diary’ which allows readers to write their own thoughts and notes next to Dawn’s words.

However, viewers were blown away by her dramatic new appearance.

Impressive: The famous comedienne, dressed in her trademark of all-black, displayed her remarkably radiant complexion as she chatted about her upcoming 60th birthday plans

The comedy legend turns 60 today and is looking better than ever.

Fans were left speechless by Dawn’s weight loss transformation and many took to Twitter to share their amazement:

Impressed: Fans immediately took to Twitter to shower praise on Dawn, admitting she looks 'lovely' as well as confident for her age (above) “Totally didn’t recognise Dawn French on #OneShow. Wow!” One user said.

“Watching the One Show with my boy, When @Dawn_French says she’ll be 60 Jojo was gobsmacked. ’60? She looks like 20’… Good boy, ay!” Another added.

A third continued: “Dawn French looks #amazingat60… Hope I look like that in 15 years’ time.”

Discussing hitting the new landmark age, Dawn told viewers of the show:

On Wednesday I am 60. How did that happen?! In the blink of an eye.” She continued: “I’m not a big one for parties, they’re not my favourite thing. I’ll sit down with my kid, my old man, my bro and my best friend and we’’ll drink too much probably. Then we’ll do some kissing and some crying and that’s how we’ll celebrate.”

She even went on to discuss she lost 7-and-a-half stone back in 2014 after undergoing a hysterectomy, as doctors claimed it would help speed up the recovery time:

When I was due to have my hysterectomy the doctor told me that if I could lose some weight before the op, they would be able to do it via keyhole, and I would recover in three weeks or so, otherwise it would be big open surgery, and three months to recover.

“So, I set about dropping a few stone. No magic wand, just tiny, joyless low-cal eating and lots more walking for weeks and weeks. It was grim. I lost seven-and-a-half stone. I could have the keyhole surgery. Great. That’s all it was, practical.”

'I hope I look like that in fifteen years!': Dawn French left fans in shock with her youthful complexion on Monday, after revealing she was turning 60 this week
Dawn also appeared on Loose Women yesterday to promote her book launch and continued to talk about her weight loss transformation with the panel:

I shed the weight a long time ago, I go up a bit, down a bit, feel no different, I’m still Dawn, I liked the old Dawn, I may go there again, depends how many doughnuts I decide to eat.” she said.
