Hear Metta World Peace 'Roar': Lakers Star Does His Best Katy Perry on 'Lip Sync Battle'

Trae Patton for Spike
Metta World Peace performs on Lip Sync Battle.

Metta World Peace will battle it out -- gladiator-style -- with Pitch Perfect star Skylar Astin this Wednesday on Spike TV's Lip Sync Battle. 

In a sneak peek from the upcoming episode, the Los Angeles Lakers player performs Katy Perry's "Roar" as he rolls onto stage in an ancient Roman-style chariot. Wearing a gold laurel crown and a very well-defined chest plate, World Peace seems intent on defying his name and bringing the fight to this battle.

Astin, meanwhile, appears to have severely underestimated his opponent. Watch below as Astin gasps at World Peace's entrance:

While Astin appears impressed (and maybe a little scared) by World Peace's grand arrival, co-host Chrissy Tiegen, likewise wearing a toga, laughs from her perch on an animatronic lion. 

The Astin-World Peace episode of Lip Sync Battle airs Wednesday at 10 p.m. ET/PT on Spike TV.
