Not sure if the following is true or not. However according to The Prodigy’s Wikipedia site:
In January 2011, The Prodigy announced that they have recorded a new track featuring vocals from the american electropop girl-group Millionaires. The song, titled ‘Atomic Bomb’ is said to be a “Grimy, fast-paced club banger which has the same infectious vibe as “Girls”…”, and will be released sometime in the summer.
