The news was revealed by KIIS FM DJ Julie Pilat who heard the track at the New York Winter Music Summit last month.
In a series of replies to Twitter questions she labelled the song "amazing" and a radio-friendly hit. She refused to give the name of the single saying "plans can change so I will let their camp reveal all details". However she added: "the song I heard has been stuck in my head ever since. Can't wait."
Aguilera is expected to capitalise on publicity surrounding The Voice's season two launch on February 5 and her new single could be released as early as next month.
