Alicia Keys is celebrating her first U.K. No. 1 album, after "The Element of Freedom" (J/Sony Music Entertainment) moved up one place on the new Official Charts Company survey. Owl City's "Fireflies" (Universal Island) started a third week atop the singles chart.

Keys' previous highest-charting album in the U.K. was her 2001 debut "Songs In A Minor," which reached No. 6. The 2003 set "The Diary of Alicia Keys" peaked at No. 13, 2005's "Unplugged" at only No. 52 and "As I Am" in 2007 at No. 11. "Empire State of Mind Part II," the current single from "Freedom," climbs 7-5 on the new Feb. 7 survey.

"Fireflies" secures a third week atop the singles chart despite a strong challenge from former "X Factor" contestants, teenage twins Jedward, who debuted at No. 2 with "Under Pressure (Ice Ice Baby)" (Sony Music Entertainment) featuring Vanilla Ice. Jedward's debut single "mashes up" Ice's 1990 chart-topper "Ice Ice Baby" with the 1980 No. 1 on which that was already based, "Under Pressure" by Queen featuring David Bowie.

"If We Ever Meet Again" (Interscope/Universal) by Timbaland featuring Katy Perry climbed 17-3 on the new chart, while RCA/Sony Music Entertainment breakthrough act Ke$ha scored a second U.K. hit as "Blah Blah Blah" entered at No. 11 and her debut album "Animal" opened at No. 8. There was also a No. 12 debut hit for Marina & the Diamonds, aka Welsh-born singer Marina Diamandis, with "Hollywood" (679/Warner Music).

As Keys moved to the top of the album chart, Dutch musician Andre Rieu's waltz collection "Forever Vienna" (Decca/Universal) climbed to a new peak, 4-2. Last week's No. 1, Paolo Nutini's "Sunny Side Up" (Atlantic/Warner Music), fell to No. 3, as Corinne Bailey Rae marked her return with "The Sea" (Virgin/EMI) at No. 5 and English-born pop artist Peter Andre entered at No. 9 with "Unconditional Love Songs" (Rhino/Warner Music).

Ke$ha now also sits atop Billboard's pan-European Hot 10 Singles chart, after "Tik Tok" climbed 2-1. Lady Gaga maintains pole position on European Albums with "The Fame" (Interscope/Universal).
