Beyonce Knowles is planning a double celebration on her 25th birthday in September (06) - she'll release her new solo album on the same day. The former DESTINY'S CHILD star's new album, B'DAY, will include her new single, DEJA VU, which features boyfriend Jay-Z. B'Day is the follow-up to Knowles' 2003 solo debut, DANGEROUSLY IN LOVE, which has sold 4.3 million copies in the US alone. That album won five 2004 Grammy Awards, tying the record for the most Grammys won in a single year by a female artist.
