As Madonna approaches 50, it appears reinvention now requires a little digital trickery.

Soft focus: Madonna is bathed in gentle lighting in her new 4 Minutes video

In the sci-fi inspired video, Madonna strips down to a skimpy corset in front of Justin Timberlake, who is almost half her age at 26.

Her flesh-coloured outfit is not unlike the infamous Jean Paul Gautier basque she wore in Express Yourself in 1989 and if the clip is to be believed, she has barely aged a day in the two decades in between.

Madonna also trade moves - and a kiss - with Timberlake in front of a giant clock performing a four-minute countdown.

The video was filmed in London two months ago and was directed by French wunderkinds Jonas and François.

Of the new clip, Madonna said only: "Goody goody gum drops."

The pulsating track, which was originally titled Four Minutes to Save the World, is the first single is off Madonna's latest album, Hard Candy, which will be released on April 29.
