Beyonce

Pop superstar Beyonce's second solo album, B'Day, has just entered the Billboard Top 200 best-selling albums chart at #1 with true first week's sales of 541,196, according to SoundScan. (The pop superstar's first solo album, 2003's Grammy-winning "Dangerously In Love," also debuted in the #1 slot, with true first week's sales of 316,846.)

The #1 US chart debut of B'Day was mirrored in Japan, where the album rocketed up the international album chart in a record-breaking 2-1/2 days after its worldwide release on September 4, Beyonce's birthday.

The international pop music icon most recently topped around the world with "Deja Vu" (featuring Jay-Z), the first single from B'Day.

A bona fide international sensation, "Deja Vu" became the #1 commercial single in Japan and the United Kingdom and achieved #1 Airplay in Hong Kong and Korea. The track made it to #1 on the German Club Charts, became the #1 R&B Airplay song in the Philippines and made it to #1 on major stations in Indonesia.

Back in the States, "Deja Vu" peaked at #1 on the Single Sales chart, #1 on the R&B/Hip-Hop Singles chart, and #1 on the R&B/Hip-Hop Singles Sales chart in the US, according to Billboard. "Deja Vu" was also a #1 song on iTunes.

A groundbreaking video for "Deja Vu," lensed by the world-renowned British director Sophie Muller (an MTV Music Video Award winner), was the #1 video on Yahoo!, the #1 most-streamed video at MTV.com, and the #1 video on MTV's "TRL" ("Total Request Live"). The "Deja Vu" video has also hit the #1 spot in the UK.

In addition to "Deja Vu," B'Day includes the just-released "Ring The Alarm," which Beyonce performed to show-stopping effect during a memorable appearance at this year's MTV Video Music Awards. The artist's "Check On It" video took home the MTV Video Music Award for Best R&B Video.
