Celebrating Britain’s first 4G network after having already enjoyed the luxury back in the States, Nicole Scherzinger attended the launch of EE at Battersea Power Station in London in Thursday (November 1).

The “X-Factor” UK judge looked smoldering in a black sleeveless dress with a semi-sheer skirt as she posed for photographers on the blue carpet.

However, her attire wasn’t just any gown, on Thursday she tweeted, “I’ve been asked to wear the UK’s first ever twitter dress tonight for the @EE Launch Party @BatterseaPowerStation #tweetthedress So EXCITED!”

The dress is constructed from 8 meters of the finest French silk chiffon, laden with over 500 Swarovski crystals and over 2,000 LED lights, which lights up to spell out Tweets sent in by fans in real time throughout the evening.

At the event, she also took on performing duties, singing hits like the Pussycat Dolls’ Don’t Cha and her new single.
