Justin Timberlake and Timbaland are off to London to appear in Madonna’s new video for the song "4 Minutes to Save the World." The two cowrote and coproduced the track, which is the first single off her forthcoming album (the last full LP she’ll release for Warner Bros.), due out this April. Queen M also recently shot the cover art for the album (believed to be titled Give It To Me) with renowned fashion photographer and frequent collaborator Steven Klein. As fans clamor for a glimpse at the superstar’s latest reinvention, details are starting to emerge about her new look and sound. Madonna’s stylist, B. (yes, she just goes by the initial), told Women’s Wear Daily at Chanel’s couture show on Tuesday that "Madonna’s look is going to be more edgy, more fresh — no more disco." And Warner Bros. staffers who heard the record at a listening session last month describe it as "very now." Says an insider: "For the first time, [Madonna's] not chasing the next new sound. She’s embracing what’s happening today."
