Kylie Minogue new single 'Timebomb' premieres - video
The popstar launched a countdown timer on her official website at 7am UK time on Friday (May 25), encouraging fans to tweet the hashtag #kylietimebomb to 'unlock' the audio.
Minogue was spotted on Old Compton Street in Soho, London last month filming the 'Timebomb' music video. The popstar was pictured on the back of a motorbike, wearing a leather jacket with a heart on the front.
She recently announced plans to release a Best Of collection in the UK on June 4 and in the US on June 19.
The compilation includes hits such as 'Can't Get You Out Of My Head', 'Spinning Around' and 'Wow', but does not currently feature 'Time Bomb'.
The 43-year-old has been at the Cannes Film Festival this week to promote her new movie Holy Motors.
She told reporters that she was keen to go "back to basics" for her first big-screen performance since 2001's Moulin Rouge!.
"Basically I banned my entire entourage from coming with me," she explained. "I stripped myself of being Kylie and wanted to go back to being as basic as possible. To pretty much be a blank canvas."
Minogue will perform her new single on this weekend's The Vo! ice UK results show.
'Timebomb' is available to download now exclusively through iTunes.
