Beyoncé Celebrates 25th Birthday with CD

The first single from the CD, "Déjà Vu," features a guest appearance by Knowles's longtime squeeze, Jay-Z.
B'Day – for which Knowles co-produced, wrote and arranged all the tracks – will be the successor to the former Destiny's Child singer's 2003 solo debut, Dangerously In Love. That album topped the Billboard 200, won five Grammys and has sold 4.3 million copies in the U.S., according to Nielsen SoundScan.
Knowles completed B'Day after wrapping the movie Dreamgirls, which was warmly received at a preview two weeks ago at the Cannes Film Festival. Set for a Dec. 22 release, the musical costars Jamie Foxx, Eddie Murphy, Danny Glover and Jennifer Hudson.
Speaking to reporters after the preview, Knowles said she had lost 20 lbs. to play the super-svelte Deena Jones, the lead singer of the Dreamettes – a '60s-style group loosely modeled on the Supremes.
"At the beginning (of filming), I was my normal weight," she said. "I actually gained a little bit, but then I lost 20 lbs. when I went from young Deena to old Deena. I wanted it to be something more than just make-up and hair. I wanted to see the change."
