In a hilarious introduction to the 46th annual Academy of Country Music Awards, Blake Shelton enters a candlelit hotel room singing his hit 'Who Are You When I'm Not Looking.'

Not only is the room filled with candles, it's filled with photos of Shelton's wife-to-be, Miranda Lambert. Some tricky camera movements from behind reveal a blonde woman in a white nightie, so naturally, we're led to believe that the lady on the chaise that he's serenading is her.

It's not revealed until the end of the segment that the woman in the sexy white lingerie is actually his co-host,  Reba McEntire, in a wig!

"All right Blake, that's enough rehearsal for your wedding night," she says. And with a quick "We've got a show to do," we're led into a Brad Paisley performance! Let the ACMs begin!
