Pop star Kelly Clarkson has reportedly scrapped her new album after label bosses weren't impressed with the record. The 25-year-old singer suffered a scathing attack from Sony BMG chief Clive Davis after he heard the new tracks, reports British newspaper the Daily Star. A source at the record company tells the paper, "It was an extraordinary presentation. Clive was absolutely merciless in his criticism of Kelly. "She's one of the biggest priorities on the label and her new songs were savaged." The American Idol winner has been working on the follow up to 2005s best selling album Breakaway for 18 months, but has reportedly gone back to the studio to work on new tracks.
