Love Island, Strictly Come Dancing, The X Factor, I’m A Celebrity… Get Me Out Of Here! – Flack starred on some of Britain’s biggest shows of the past decade.
However, at the time of her death her career was under a cloud after she was replaced for the winter series of ITV’s Love Island after being charged with assaulting her boyfriend.
Many fans first got to know her bubbly, likeable personality when she joined Sam and Mark to front the zany Saturday morning children’s show TMi in 2007.
From there, she joined Ian Wright when Sky One revived game show Gladiators, and became one of the hosts of I’m A Celebrity… Get Me Out Of Here Now! in 2009.
She went on to host another ITV spin-off, The Xtra Factor, two years later, before being chosen to front a series of the main talent show itself with Olly Murs in 2015.
She confirmed her popular appeal when she won Strictly with dance partner Pasha Kovalev, fending off competition from Frankie Bridge and Simon Webbe.
But she talked about the difficulties she faced after lifting the glitterball trophy, saying: “I couldn’t get up and just couldn’t pick myself up at all that next year.”
When Love Island was relaunched in 2015, she was the natural choice to host, and she helped make it one of the biggest shows on British TV.
The first few series performed well, but the show really became a TV phenomenon from 2018, particularly among younger viewers.
When the show won the Bafta for best reality show that year, she picked up the award.
Flack made her West End stage debut as Roxie Hart in Chicago in 2018, starred in a touring version of Crazy For You, and appeared on the celebrity version of The Great British Bake Off.
