For the party held at Battersea Power Station in London, The X Factor judge wore the unique garment made from eight meters of the finest French silk chiffon, laced with over 500 Swarovski crystals and more than 2,000 LED lights.
Using the LED lights, the dress displayed messages from fans sent in real time throughout the event via @EE and #tweetthedress. It was created by fashion design agency Cute Circuit, whose clients include U2 and Katy Perry.
Alongside wearing people's tweets, Scherzinger also performed a medley of her most popular hits, including Pussycat Dolls track 'Don't Cha' and her new solo single.
"Had so much fun performing at @EE Launch Party last night!! Thank you for all of your tweets & support! #4GEE," the Hawaiian-born star tweeted today.
Also entertaining fans on the night were digital magician Marco Tempest and a set from DJ Yoda.
London's skyline was lit up as EE - the joint venture of Orange and T-Mobile - trumpeted the launch of 4G mobile in 11 UK cities earlier in the week. The technology can deliver internet speeds on mobile devices up to five times faster than 3G.
A 4D Light Show was held at History at Battersea Power Station, beaming the projection across the entire 8,000 square meters façade of the former power station on a specifically built screen the size of an Olympic swimming pool.
The five-minute projection showed hundreds of specially animated light particles - representing the EE network - and was supported by a score created by DJ Yoda.
Hosting the night was actor James Nesbitt with a host of celebrities from the world of art, culture, sport and television, including Stephen Fry, Jonathan Ross, Pixie Lott, Dame Kelly Holmes, Jimmy Carr, Jaime Winstone, Dionne Bromfield, Louis Spence and cast members of The Only Way Is Essex and Made in Chelsea.
"We wanted to mark the arrival of the UKs superfast network with something as spectacular as the speed of 4G," said Steven Day, the chief of brands and communications at EE.
"Just as Battersea Power station leaves behind a legacy in British history, so too will the arrival of 4G in the UK so we thought it was a fitting backdrop to mark its switch-on."
