Alexandra Burke's debut single "Hallelujah" (Syco/Sony Music Entertainment) has joined an exclusive club of top-selling singles artists in the U.K. after less than four weeks.

According to the Official Charts Co, the cover of the Leonard Cohen song by the winner of music TV talent show "The X Factor" has sold 17,645 copies so far this week. Its total sale since its release on Dec. 14 is 1.027 million.

It means that Burke now has one of only 10 million-selling singles of the new millennium. She is at ninth place in the list of million-sellers, ahead of children's favorite "Can You Fix It" (BBC) by Bob The Builder.

Will Young, a former winner of "Pop Idol" in the U.K., has the biggest-selling single of the millennium with sales of 1.79 million for "Anything Is Possible/Evergreen" (RCA).
