Team GB heroes Beth Tweddle, Greg Rutherford and Luke Campbell will be flicking the switch of the Blackpool Illuminations this evening.
Liverpool gymnast Beth Tweddle won a bronze medal on the uneven bars, making her the most decorated British gymnast in history.
Beth said: "I'm really looking forward to turning the lights on in Blackpool.
“It is going to be an amazing night and something special as I am a local North West girl.
“I hope everyone can join us for what is going to be a fab evening.”
This year marks 100 years of Blackpool Illuminations and the switch-on is to be held on the Festival Headland near Blackpool Tower for the first time.
Natalie Wyatt, Managing Director of Marketing Blackpool, said: "2012 is a platinum year for Blackpool Illuminations as it is the Centenary of our world-famous Lights, so it is only fitting that some of our British Olympic heroes kick off the celebrations for us.
"We couldn't be more delighted to be welcoming such an incredible group of people to officially Switch-On the Lights.
"2012 is a year which the whole of Great Britain will remember so it is wonderful that Blackpool's historic year will also be celebrated with such inspiring people."
X-Factor winning girl-band Little Mix will be performing for an estimated 20,000 people, joined by Lemar, Amy MacDonald, Lawson, Paloma Faith, Scouting For Girls, Noisettes, Blackpool singer-songwriter Karima Francis, boyband Loveable Rogues and girl group Vanquish.
