WATCH: Victoria's Secret Angels Lip-sync with Justin Bieber

T-minus 4 days until the Victoria's Secret Fashion Show airs on CBS, and what better way to get amped to see girls strut around in wings and panties than by watching the Angels lip-sync to Justin Bieber's "Beauty & a Beat?"

It's a bit awkward at times, especially when the Angels (ahem, Jessica Hart) don't know the words, but it's entertaining nonetheless. Watch as Alessandra Ambrosio, Adriana Lima, Doutzen Kroes, Elsa Hosk, Erin Heatherton, Behati Prinsloo, Lily Aldridge and more whip their hair around with some major Bieber fever.

Tune in to see the complete show on Tuesday, December 4th at 10pm on CBS.
