Over the years she has undergone a host of transformations.

And Anne Robinson appears to have once again replenished her look as she was spotted out in London on Monday looking barely recognisable. 

The 71-year-old former Weakest Link presenter looked stylish in a simple black ensemble yet her face appeared puffy, with her eyes slightly hooded.

Anne has been candid about undergoing plastic surgery in the past, admitting to a penchant for botox and having a facelift. 

While her image has changed vastly through her time in the spotlight, with a career spanning over three decades, this appears to be her biggest change to date. 

As she departed a West London hair salon, the Lancashire-born star exhibited her perfectly coiffed trademark red tresses, which framed her new look. 

Her eyes were heavily outlined in black kohl while her foundation was heavily-applied, yet her well made-up face failed to disguise the new appearance beneath. 

MailOnline has contacted a representative for Anne for comment.  

In 2009, Anne opened up about her surgery to Daily Mirror, saying: 'I had a facelift originally five years ago because I didn’t want to look like my mother. I did look like her.

'I certainly wasn’t scared when I had my facelift. Why would I be when I nearly died of alcoholism 35 years ago? I never thought it was a big deal to have it done. And I’ve never thought to keep it quiet.'

Speaking again of her surgery, she candidly admitted she would be open if she had more surgery: 'Of course I would say if I had had more surgery. I don’t think people are jealous. But I do think women are interested and that’s why I’ve always told the truth.

'Anything that allows women to feel better about themselves is worth the money.' 

Last year when Anne once again showed a contrasting look, Dr Mabroor Bhatty of Transform Cosmetic Surgery said: 'She's been very open in the past about having a face lift and I suspect she may have had another one.

He added: 'I wouldn't be surprised if she's had a neck lift to keep her jaw nice and defined. The treatments and procedures have worked well for her but age and gravity can't be kept at bay forever.'

The presenter once said: 'My appearance is all down to maintenance. I'm like the Forth Rail Bridge.

'I run, I have facials, I eat an awful lot of salmon and salad. If you want to expose bare arms in primetime, there's no choice.'

She also once defended her use of Botox, saying: ‘Do you know that the average woman of my age is sized between 16 and 18 and has at least two chins? 

'I’ve nothing against that, but you can’t simply talk about age - you have to look at the restrictions of television.’ 

Later in the day it was apparent why Anne was headed to the hairdressers as she stepped out with her daughter Emma Wilson to go to The Man Booker Prize International Ceremony in London. 

The swollen nature of her face appeared to have reduced yet she still lathered on a heavy mask of cosmetics. 

Sporting a youthful ensemble, Anne looked lovely as she joined her pretty daughter at the bash.
