LOS ANGELES (Billboard) - Rookie pop singer Ke$ha ended Susan Boyle's six-week reign on the U.S. pop album chart Wednesday, and also logged a fourth week at No. 1 on Billboard's singles chart.
Ke$ha (real name: Kesha Sebert) becomes the first artist to lead both charts simultaneously with debut recordings since British pop singer Leona Lewis in April 2008.
Her RCA Records label said Ke$ha's album "Animal" sold 151,942 copies during the week ended January 10, citing data from Nielsen SoundScan. Boyle's "I Dreamed a Dream" slipped to No. 2 on the Billboard 200 with 93,000.
On Billboard's Hot 100 singles chart, "TiK ToK" led the field, while her follow-up single "Blah Blah Blah" debuted at No. 7. The tunes claimed the top spots on Billboard's Digital Songs chart, making Ke$ha the first artist to accomplish that feat with her first two singles and the first to do so at all since the Black Eyed Peas in July.
Elsewhere on the Billboard 200, Lady Gaga's "The Fame" dropped one rung to No. 3 with 66,000, while Alicia Keys' "The Element of Freedom" (62,000) and Mary J. Blige's "Stronger With Each Tear" (47,000) were each also down one, to Nos. 4 and 5, respectively.
The "Alvin and the Chipmunks: The Squeakquel" soundtrack jumped one to No. 6 (44,000), Taylor Swift's "Fearless" fell two to No. 7 (38,000) and the Black Eyed Peas' "The E.N.D." held steady at No. 8 (36,000).
Justin Bieber's "My World" fell three to No. 9 (34,000), and Lady Gaga's "The Fame Monster" slipped one to No. 10 (31,000).
Overall album sales totaled 5.92 million units, down 24 percent from the previous week, and down 5 percent compared to the comparable sales week of 2009.
