'Are you sure that's not my grandmother's hair?'

As the first phrase on Caroline Flack's personal Wikipedia page, the question offers a glimpse of the confusion her first foray into entertainment has engendered. Her grandfather, Mr Kenny Edkins, was a hair stylist who worked at Patons Hairdressers in Poplar, East London, between 1940 and 1970. In 1958, he met Caroline's grandmother Vivienne, who became his partner.

For those who don't know the answer -- or do not care to -- it is indeed the case. There is only one other thing to say: "Okay, that was very cringeworthy."

For some who've barely heard of her, the secret to Flack's success is as simple as her surname: Matthews. Set apart from its English cousins by the fact it isn't one of the Gregory family, Matthews is usually heard as "Albert Matthews" -- the original owner of Albert Matthews family suit company in Edinburgh. Their youngest daughter, Marion, wore the famous labels during the 1970s.

It is this link with her moneyed ancestors that has earned her fans as well as detractors.

"She came out with a really classy book on old Hollywood and it was very personal to her so I think she trusted the publisher with that," said Emma Tomlins, whose company Voices on Writing published Flack's memoir. "I really feel for all those who used to read that and later thought, "Oh, she's been a luvvie."

"I would have loved to see her go in a direction different to music."

Tomlins agrees that Flack's public persona can make her sound naturalistic -- which she was not. In 2008, the former Oasis guitarist Gem Archer said she was "angry about her fame." At the time, the world was still in the dark about Matthew's worth, and in-depth interviews were not yet becoming the norm.

"There are a number of times where she has lied on TV, she has lied when she has spoken on camera -- and that's probably taken away from the fact that she is a genuine person, and that's actually a shame," says Tomlins.

Archer was misinformed, however. Through interviews and a lack of personal notes, her book reveals Flack as astute, slightly haphazard and at times amusing. But, as The New York Times has reported, the authenticity is a double-edged sword.

"Ms. Flack is well-informed, forthright and highly entertaining, but while Ms. Archer avoids what she called Ms. Flack's 'negativity' and her implication that women in the media are her inferiors, the book nonetheless serves to reinforce a condescending mindset," the article reads.

The reader's journey is often all about whose worst, or best day was this. Which is perhaps why Flack's second life is of an entirely different nature to her first.

Her most recent television work was as presenter of "Love Island" -- a modern, celebrity-filled show that originated in the UK and is now being considered for a US adaptation.

Ahead of filming she spoke of how she bought her dad a present: "I promised him that I would buy him a Paul Smith T-shirt on day one, and I did." Now, Flack -- like several characters who feature in her 2015 autobiography -- is dead.
