NEW YORK (Billboard) - Dance-pop singer Lady GaGa earned her first No. 1 on Billboard Hot 100 singles chart Thursday with her Grammy-nominated tune "Just Dance."

At 22 weeks, the song makes the longest trip to the top since Creed's "With Arms Wide Open" (27 weeks) in November 2000. Yonkers-born Lady GaGa (birth name: Joanne Stefani Germanotta) will compete for the best dance recording award at the Grammys on February 8.

After four weeks at No. 1, Beyonce's "Single Ladies (Put a Ring on It)," dropped to No. 2, swapping places with Lady GaGa. T.I.'s "Live Your Life" featuring Rihanna held at No. 3.

Albums chart champ Taylor Swift's "Love Story" rose one place to No. 4, flip-flopping with Kanye West's "Heartless." Katy Perry's "Hot N Cold" remained at No. 6, and Jason Mraz's "I'm Yours" jumped five places to No. 7.

Britney Spears' "Womanizer" fell one to No. 8, Kevin Rudolf's "Let It Rock" featuring Lil Wayne rose three to No. 9, and West's "Love Lockdown," dropped four to No. 10.

For the first time since January 1998, the Hot 100 does not have a debut; the only additions to the list this week are re-entries.
