Watch Terry McDermott and Blake Shelton sing Aerosmith's "Dude Looks Like a Lady" on The Voice Season 3 Live Finale, Dec. 17, 2012 (VIDEO)

Terry McDermott and his coach Blake Shelton teamed up for a rockin' rendition of Aerosmith’s “Dude Looks Like a Lady” on The Voice Season 3 tonight, Dec. 17, 2012 — and we're not just talking about the unlikely pair's hot vocal performance!

Coach Adam Levine stole the show with a surprise appearance, wearing nothing but a pair of jeans and a long, red wig as he rocked out on the electric guitar. But we'd be remiss if we didn't mention Terry and Blake's stellar performance, which got coach Cee Lo Green out of his chair and on his feet.

With the new setup, fans can vote for their favorite contestants by calling in, voting on Facebook or NBC.com, texting (for Sprint users), or by buying their song on iTunes. If you want Terry to win The Voice, be sure to vote at the end of the show!
