DESPITE an unusually aggressive promotion schedule, Kylie Minogue has bombed in the United States with her first album in four years.

“X,” the Australian pop singer’s fourth U.S. release and 10th overall, debuted at No. 139 on the Billboard 200 with sales of just 6,000 copies, according to Nielsen SoundScan.

Her previous album, “Body Language,” debuted at No. 42 with 43,000 copies in 2004. Two years earlier, “Fever” bowed at No. 3 after selling 114,700 copies.

Minogue, 39, was sidelined for two years after being diagnosed with breast cancer in 2005. She was in the United States the week of the album’s April 1 release, doing TV interviews on NBC’s “Today,” CBS’ “The Late Late Show With Craig Ferguson” and the syndicated “Ellen DeGeneres Show.” She also sang on ABC’s “Dancing With the Stars,” which was seen by more than 17 million people.

“X” was released internationally last November, debuting at No. 2 in Britain and No. 1 in Australia, her third chart-topper Down Under.

Minogue’s international fame is not exactly replicated in the United States, where such albums as 2000’s “Light Years” and 1990’s “Enjoy Yourself” were not even released. Her only other Billboard 200 appearance was with her 1988 debut, “Kylie,” which peaked at No. 53.

A spokesman for Capitol Records, which released “X” in partnership with dance label Astralwerks, said a lot of Minogue’s core fans in the United States bought imported copies of the album last year. (SD-Agencies)
