Beyoncé knows that if something ain't broke, there's no need to fix it. The Destiny's Child diva just dropped 'Déjà Vu,' the first single from her new album 'B'Day' (due in September), and the title of the song speaks volumes.

Much like 'Crazy in Love,' the jam that kicked off her first solo effort, this Rodney Jerkins-produced groove also features her longtime beau (and hardly "retired" rapper) Jay-Z on the mic. As expected, the song is a bouncy, hook-laden pop monster that features B and Hov flirting over sampled horns and soulful R&B rhythms.

'B'Day' also features production from hip hop heavy-hitters the Neptunes and Swizz Beatz and is cleverly scheduled for release on September 5 -- the day after her 25th birthday.
