Among the stars going mic-to-mic, Bieber channels a heavy metal icon, and Taraji P. Henson has a secret weapon

Justin Bieber may win the Battle, but will he win the war?

The singer is just one of many stars who’ll we’ll see revel in victory or collapse in defeat when Lip Sync Battle returns to finish its Internet-breaking first season.

Among the highlights of a new promo for the second half of the season, Bieber goes off the rails to channel Ozzy Osbourne – including a heapin’ helpin’ of guyliner and a black wig – as he performs the rocker’s classic “Crazy Train (Speak of the Devil).”

Empire‘s Cookie and Lucious (a.k.a. Taraji P. Henson and Terrence Howard) also go mic-to-mic. Howard dons a Rick James-esque wig and a get-up composed of sequins and mesh as he sings the Commodores’ “Brick House,” but it’s Henson who has a secret weapon (spoiler: Mary J. Blige).

Other celebrity competitors this season include Iggy Azalea and her fiancé Nick Young, plus Will Arnett, Victoria Justice, Deion Sanders and Community star Alison Brie (who looks like she’s giving Nicki Minaj a serious run for her money).
