Kylie Minogue is set to celebrate her 44th birthday by giving her fans a present.

Minogue released a brand new single, Time Bomb, on Friday, three days before her birthday.

Her website is running a countdown until the song’s premiere, with fans required to tweet to unlock the song.

Minogue will perform the new song on the UK version of The Voice this weekend.

A video for the song, said to be an upbeat pop track, was filmed in London last month.

Time Bomb is a stand-alone release, and does not appear on her upcoming singles compilation, released in June.

It is the latest surprise move in Minogue’s year of celebrating her 25th anniversary making music.

Diehard fans were treated to an “anti-tour” filled with b-sides, album tracks and unreleased songs.

A DVD of Minogue’s Melbourne Anti-tour is expected to be released this year.

There is also an album’s worth of her hits recorded with an orchestra in London last year on the horizon.
